Now imagine that tomorrow I package my own version of Stockfish, with some changes in the graphical appearance, and sell it on the App Store for $0.99. And I comply with the GPL: I make the source code available to any CUSTOMER who asks for it so I'm in perfect accordance with the law.

Could you please tell me if you are going to complain about this, and if so, why?


You are missing the fact that this isn't about the GPL or about copyright rules. I agree with you that most of these programs don't violate the license or any copyright laws. I even pointed this out in the very message you replied to. The point is that these apps very clearly violate Apple's own App Store rules. They do not allow apps which are copies of another developer's work, and state in their guidelines that such apps will not just get deleted from the store, the developers will also be expelled from the developer program. My impression is that Apple takes matters like this very seriously, and I am quite sure they will take action if the clones are brought to their attention.



I'm sorry I don't see anything like that in the App Store Guidelines.

There is a part that talks about copying another developper's work, but I think it's about illegal copying.

In the case of a legal derivative of a GPL program I think it's clearly different. Apple clearly knows about them, as some of them clearly state what they are, and just lets them be.

These derivatives are actually pouring money in Apple's coffers. I think you will have to demonstrate that they are seriously violating some law before they pull them from the App Store.

As to why I care at all: I wouldn't care much as long as the clones were free, but by charging for a program also available for free, they are effectively stealing their customers' money. Arguably they are stealing a tiny bit of your money too, since another commercial chess program may mean a handful of less sales for Chess Tiger. It is true that I am not hurt by these programs in any way, but I care about other people, too.

What you are saying is that charging for a program available for free is stealing.

You are in essence saying that the GPL explicitely allows and encourage stealing.

If you have a problem with someone selling a GPLed program, then you have a problem with the GPL.

This is an exerpt from the preamble of the GPL licence:

Code:

  The licenses for most software and other practical works are designed
to take away your freedom to share and change the works.  By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users.  We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors.  You can apply it to
your programs, too.

  When we speak of free software, we are referring to freedom, not
price.  Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.



The fact that you are the author of a GPL program does not give you the right to prevent others from selling it.

By releasing Stockfish under the GPL licence you have given up the right to prevent anyone from selling it.

Stockfish is not under your control anymore. You cannot dictate what others can do or cannot do with it. If you are not pleased with it, it's too late.
