CAINER  OK maybe "deceptive" is a little strong and maybe I read too much into it, but nevertheless there is contradiction:

Either is it FREE-ware or it is DONATION-ware

Since the author has purposely coded CyberDuck to display a "Please donate" message every time you quit it, then he wants donations, and therefore this is donation-ware.

In contrast, see FileZilla. This is also marked as Free-ware. It does not *ever* ask you for a donation. Ever. Sure, you can donate if you want, but the app itself is not begging you for it.

So if CyberDuck truly is Free-ware then the author should do the right thing and remove the nag screen asking for a donation. Am I wrong?

CAINER  It's never been "free" but always marketed as such. I suppose that might be called clever marketing. I call it deceptive, quite honestly. It's always been "donation-ware": The author would like you to donate, and asks you to do so. If it were truly free, there would be no such request.

CAINER  Support developers by paying them for the work they do.

Do you work for no pay?

Other FTP apps have been allowing editing with an app of your choice for years, even before ForkLift ever existed.

CAINER  To the dev: If you make a public beta release then you've got to expect people to report bugs in public places. Make a private beta if you don't want that.

CAINER  Except that the UI is f-ing ugly as hell! Well, I guess it is free after all...

But for my money (and that's $5 cheaper than Transmit, btw) take a look at Yummy FTP. You get a Transmit-like UI *and* it's a rock solid performer. Never let me down so far!
