So, who may i contact to obtain the source code?
Even if you disregard my comment, you should at least comply to the most easy parts of the licenses used here; to give Credits to the copyright holders, that most of the libraries used demands according to the licenses.
To give one example. You use older versions of libpoppler, that goes under GPL v2. As it states in the README file, that are not present in your build:
”Please note that xpdf, and thus poppler, is licensed under the GPL,
not the LGPL. Consequently, any application using poppler must also
be licensed under the GPL.” .
Also, you claim this is 5x faster than other eBook converters, which i find very hard to believe, as the underpinnings is almost the same as Calibre, alas reorganized and boosts less features. An as it seems, there are plenty of apps clones and look almost the same as this, both on Windows and Mac and do the same stuff. Also, the webpages for the products, including yours almost always is built the same way, uses the exact same ”selling texts”. But more interesting, most webpages (including yours) also have a link page with links to ”friends” or ”recommended software” that for some reason always include Wondershare.
As your software and the identical clones uses the exact same strategy as the applications by Wondershare that goes under different brands and names, you may not be surprised that i believe that you may belong to this category. The company on your page, that holds the ”copyright”, don't even exist.
But it gives a feeling that it's based in Europe or Japan. However, the traffic from the site mostly comes from a large Chinese Social Media site (think Facebook), and somehow, the ones ”reviewing” this app, and some of the Wondershare ones (including the Wondershare owned clone Brands iSkySoft and so on), seems to be the same persons. On some occasions, they reviewed or gave tips on other software, but always with a ”but these are slower or not as good as product X”. This is a pattern you see on english based sites and forums also.
It's not that hard to see which of the users that are fake ones. Somehow cute when you see the use of Shutterstock photos added to the ”profile” of the raving reviews.
And the fact that you, the ones that made this app and others, hide who owns the domain via the GoDaddy service Domainbyproxy don't really feel like a good thing to do, as it feels like you are hiding something.
Cheers.
Thanks for you comments.
1. Epubor all products are produced by Epubor team, we have our technical center. We are not an affiliate of other software company such as Wondersahre.
You can visit Wondershare site and their affiliates such as iSkysoft, you will find that their products are nearly the same, just using different name and logo. But they don't have eBooks related tool, they have converters tool but are about videos, not the eBooks. And their PDF tool is also different from Epubor. I suggest you try to using our products and others at first.
2. This is our Link page, no Wondershare including. It just lists our partners such as software download and review site.

4. You may see other site are with the same design of Epubor, such as TunesKit. In fact I've contacted them they said they will update and fix the problem, but until now they haven't do as they promised me.
5. We are a company in China, but 90% of our customers are focused on English speaking countries, and Japan.
I'm sorry to say that either you don't know the contents of your applications, or that you do know.
Let's break it down shall we?
1. The interesting thing here is that doing a quick search for similar software (in this case jut Mac apps), i found a dozens of applications with a similar UI. While the UI don't say so much about the code, i downloaded them all and analyzed them in a VM Sandbox. Everyone of them did not respect the OpenSource Licenses used. Most of had traces from the same developer.
But ok, not everyone used a python wrapper, some of the applications used different build environments and outputs.
But concentrating on this application there are lot's of issues. First, the package installer from your site is not signed (there are no reason for not signing). Secondary, you don't need an installer for this kind of software.
But that would be easy to fix for you.
Furthermore, you claim that you produce all products. While you may have, you have not developed very much except building a wrapper to the various OpenSource code you have used. And yes, that includes Calibre. Why else would code form Calibre show up (even if the code from Calibre you are using is quite outdated) along with the copyright notice from Kovid Goyal?
And to continue, if we skip all the ”minor” OpenSource code used, you are using the OpenSource DeDRM_tools aand many other tools that are under a OpenSource License. Just comparing the contents inside shows that most of your apps using 3rd party copyrighted code (many of the OpenSource Licenses used is not free as in beer).
1b. Regarding the websites, there not some, but many. I counted 58 before i gave up. All of them using the same kind of information, same stock images from the same Shutterstock series, same ”recommended” software (depending on the type of SW. Most of them are in the category of downloaders, converters and readers) the from known adware infested sites like Softwareinformer and such. When mapping all the crosslinks, i came up with a very distinct pattern.
But ok, i will withdraw my comment about this, as it will not show any hard proof.
2. See (1). Also. The sites you referring to i count at least 5 of them hold by Wondershare (in that sense that their software connects to same IPs as Wondershare branded equivalents and in some cases have certificates from Wondershare). 100% of them breaking numerous of OpenSource Licenses. The 3rd party Software sites, such as review sites and lists you link to are frequently found in Security blacklists. One of them is owned by a known ”cyber” criminal in Eastern Europe with ties to organized crime.
Another friend you link to, that happens to sit in the same building as you (yes, i know, there are plenty of companies in the building, i'll actually been in the building in person on a different matter), has software that has the share both UI and code from another Chinese software company that is owned by yet another one who's name has been mentioned earlier.
Add to this (!), that two other software companies shows up when studying outgoing traffic from your software (while not directly, see below). Strangely enough they are registered the same day as your domain and shares your IP address. Mapping the traffic, you see that the IP range used by the software companies (including yours) is identical. One of the companies (or brands) just happens to have software that is nearly identical to the one mentioned developed by the ones sitting in the same building as you.
The Kindle manager (also using Open Source tools breaking and not complying to the licenses) one on the third software ”company” that shares the same IP ranges as you, was, at least a couple of months ago using ”Epubor Inc.” in the info for the installer for Windows.
3. Yes, but there is no company registered in that name neither Mainland China - Hubei, HK, Taiwan, U.S.A. or the U.K. It's listed on many company lookup sites, but most of them are submissions and scrapers from other sites that are using submissions. Also, the domain is by proxy, which is shady for a software company that want to be taken serious.
4. Ok.
5. To be frank, i would say paying customers, but that you know better than me.
A recommendation. Respect the Open Source licenses, as i said before, there is no problems with selling Open Source SW really. Apple, Adobe and others to this all the time. Be honest what company that is behind the SW. Don't use different ”names”/”brands”. Also, skip the greyhat and blackhat SEO methods (even if affiliates is the cause mostly, you still have big problems). Skip ”testimonies” using fake personas.
Actually, i want companies like yours to contribute and strive and succeed. But then you must change some of the ways you are using. I may sound angry, but really not.
“If you make a mistake and do not correct it, this is called a mistake.”
― Confucius
Thanks for your kind reply.
I know you are not angry, and I understand that you just wish we could respect customers and other developers. We will, and thank you.
1. I said our software is 5X faster than others, this is mean that our software using eCore, and eCore's main function and good point is DRM Removing especially for Kindle books.
2. You must admit that Epubor products are much easier to use than others like Calibre because we are with clean interface, no need to install any plugins, and in fact 90% of our customers are those people who are computer beginners and wish a simple tool to remove DRM, not to manage all their books.
3. Sorry that our tool really use third-party codes when converting books to PDF or converting PDF to other formats.
This is my pleasure to see your comments, we will fix our problems.
I'm sorry for causing you so much inconvenience.
Now we've resolved the problem because now you can directly download Epubor Ultimate from Macupdate Server, not from Epubor server. So, won't happen similar problems of timeout downloading or low speed downloading.
Thank you.
2. This converter is just over 1MB, while Calibre's conversion core is over 100MB.
3. At least 5x faster than other eBook converters.
