Charges way too much: seems to be competitive with other paid apps in this category.
Freely available elsewhere: only if you're willing to roll back three full versions of Mac OS X.
Not changing or adding much: it's a PDF unlocker, it unlocks PDFs -- there's nothing to add.
Charging way too much for tiny incremental upgrades: the last charge was $6 for the upgrade from 2.x to 3.x and that was 6 years ago, right?
Prey on the unsuspecting: color me unsuspecting, then. I researched the market, looked at my options and chose an app that was supported, looked nice, did the job, and had favorable reviews from reasonable people. I chose this PDFKey Pro.

I also have a bunch of PDFs which I could not print or extract single pages. After squeezing them through PDF Key Pro, I can do all those things.
Works great and received several updates. If you need this kind of software, PDF Key is a good joice.

If you can use a terminal, it comes with a program, pdfclean, that will do the exact same thing.

It has UNlocked every PDF that I thrown at it.
It is trivial to use.
Highly recommended.

If your app can just break it.

Where is the protection if there is at least one (free!) app in the world that can break it with no effort?
