License Non-Compliance of some iOS apps

[nguyenpham]

When finding some information to write a wiki page, I realize that some iOS apps don't respect the Stockfish license, which requires all software embedding its code to be open source and publish links to their source code.

Just list a few iOS apps after a quick search. I am sure the full list must be much longer. They all say clearly they are using Stockfish:

• SmallFish Chess for Stockfish: it is a huge surprise since this app is considered an official one when its name is published on the Stockfish homepage
• Chess Move - Stockfish Engine
• Syzygy Tablebase for Stockfish
• Chessvision.ai Chess Scanner
• Analyze This Chess
• Arkon: Chess Opening Explorer
• Imperial Chess
• iPlay Chess
• Pocket Chess Book
• Ulimate Chess League

Correct me if you find any wrong. Add more if you could.

I can't speak for literally anything else, but from looking at the screenshots it looks like chessvision just opens lichess to analyze, which should have everything correctly handled.
