My message to the list yesterday seems to have not gone through, but
here's my (IANAL) understanding of the situation:

Unless Apple has changed its policy, the App Store terms of use impose
restrictions beyond that of the software's license, which violates any
version of the GPL, even with the source code. Moreover, iOS does not
allow the user to install unsigned software, so even if the user can
modify the software they can not run it in iOS. GPLv2 allows this, but
the loophole was closed in GPLv3. In order to legally distribute
GPL-licensed software through the App Store, all contributors (unless
they have signed a CLA) must agree to relicense the iOS version of the
software or make an exception to the license. Nextcloud is an example of
the latter.[1] I'm not familiar with Stockfish and am not sure what
their situation is.
