Apparently someone is trying to make money with an Android application that I wrote a month ago. At first I was really mad about people ripping off others by making money of other people's work. But today I actually feel it is a bit of a compliment. At least this guy thinks, my little app is worth some money. ;-)
But seriously, of course I complained about it to Google with their DMCA form.
Regarding the GPL and selling software: this is actually possible, as long as you respect the terms of the license. Paragraph 4 of the GPL says:
You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.
Update: Google removed the App. And it seems to me that they removed the vendor's account all together.
Update 2: After Google removed it the first time, the guy created a new merchant account and uploaded my app again. I filed a DMCA complain again and Google took down the app and his account a second time. But this guy is really persistent: On August 16th he uploaded the app AGAIN. Remember: He has to pay 25 US$ everytime he creates a new account. And he does this to try selling an app (of about 50 LoC) for 2$, that I give away for free. How stupid can one single person be? I would have thought you'd need at least ten *really* stupid people to gather that amount of idiocy.
