The GPL is a license to use copyrighted material that you otherwise  
would not have any legal right to use.  If the author of GPL software  
posts their software to the appstore, it could be read as a implied  
statement that the author is not going to enforce all aspects of the  
GPL.  An explicit statement to that effect would be better.

If you don't own the copyright, then that is not your decision to make.



Programs should be written for people to read, and only incidentally  
for machines to execute.
