'Clone' is not a term you will find in the GPL. The GPL specifies it is only allowed to use GPL code in applications that are themselves open-source and GPL. If the source code of the apps is released under the GPL, the makers of these apps are perfectly allowed to sell them. If not, and they are not willing to provide the source code, then the use of the GPL'ed Stockfish code was a copyright infringement, and its use an act punishable by law.

I had seen a clone of Droidfish app in the Google Play Store with the name "iChess" (same as my app name!)
I reported it to Google and also sent an email to the dev.
It is now offline. https://play.google.com/store/apps/deta ... ess.ichess
