The distribution controls and market requirements are unfortunate, but if they are being imposed on you by a platform owner then it's that vendor's fault. Those app store agreements are absolutely loaded with commercial restrictions. Please don't pin the blame for this on copyleft licensing, when those vendors have explicitly decided they were against it long ago and would do everything they could to stop it including banning it from their platforms in an effort to destroy the commercial viability of what they view as competition.
