The software is based on Gifsicle, itself a GPLv2 licensed piece of software, so there isn't much the author could legally do about it.
This comment section is filled with weird misconceptions about the software and about the compatibility between GPL and the Apple store terms of service. Somehow people think the software is GPLv3 even though a cursory glance will reveal that it isn't. People think that the author of the modification has a say in how it's licensed. It's based on GPLv2 software, he doesn't. Others are saying that while distributing GPLv2 licensed software on the Apple store is fine, GPLv3 isn't, when neither is OK. Sorry for soapboxing here, but it seems appropriate to address all these misconceptions in one place.
