Technically I am not sure there is a GPL violation here, because the source code doesn't seem to have been modified at all, which means that the source code
is available.
On the other hand, these apps clearly
do violate Apple's iOS App Store rules. If they include Bryan Whitby's "Modern" piece set, they are also guilty of using his art without the author's permission.
I don't know whether they got an exception from the authors.
They did not.
I think the StockFish team should do something about it, but it's up to them.
I am trying to do something about it. I contacted Apple concerning "Deep Fish" yesterday (without receiving a reply so far), and will inform them about the other clones Julien mentioned (and by the way, thanks for bringing them to my attention!) as soon as possible. I used the "Contracts and Legal" => "Rights Infringement" form on the iTunes Connect web site to report Deep Fish. If anyone knows a better way to contact Apple against issues like this, please let me know.
I would also appreciate if those who have downloaded some of these apps could help by writing a review and explain that these apps are clones, and complain directly to Apple if you know a good way to contact them.
Tord, you are joking, right?
You DID read the GPL before publishing Stockfish under this licence, did you?
You did not miss the part where it says that it is LEGAL to sell a GPL program as long as you comply with the GPL: in order to do so you just have to provide your source code to any CUSTOMER who ASKS FOR IT.
Technically they are not in violation until they refuse to send you the source code. Did you contact them and ask for the sources? Oh and be sure to purchase their product before asking, because they don't have to make it available to you if you do not possess their product.
If they are in violation because they are using graphics made by someone else, it's not your business. The author of the graphics has to ask them to stop using the graphics, or sue if he feels like spending a few thousands of dollars in legal action. Or ask Apple to do something... Good luck with this.
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?
