Apple's App Store Review Guidelines wrote:If you attempt to cheat the system (for example, by trying to trick the review process, steal data from users, copy another developer's work, or manipulate the ratings) your apps will be removed from the store and you will be expelled from the developer program.You think it is. I think it is not. What they truly meant, only Apple can tell. All I can do is inform Apple about what is happening, and they decide what to do. If your interpretation turns out to be the correct one, it's of course not a problem to me. The existence of commercial copies of Stockfish on the App Store obviously doesn't harm me in any way. It only harms customers and authors of other commercial chess programs on the App Store. If and when someone complains to me about such clones, I can tell them that I have informed Apple, and that they seem to be OK with it.tiger wrote:but I think it's about illegal copying.
Once again, this isn't about the GPL at all. Nor is it about what I am pleased or not pleased with. It's entirely about Apple's rules. I'm providing Apple with the information they need to decide whether some programs conform to those rules, nothing more and nothing less.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.
Gian-Carlo has pointed out that the GPL is incompatible with the App Store licensing agreement, so it seems after all that you DO have some control on this.
I would really like to see you taking responsability about the issue.
Instead of hiding behind Apple's rules now, while you were apparently against the practice in an earlier post, please state clearly your stance on the matter.
Is it OK or not, in a general context, to charge for a copy of Stockfish (either the engine alone or the engine and some GUI), without your explicit consent, provided that the seller abides by the GPL terms?
This is not a thoretical question. I'm considering distributing Stockfish and charging for it.
