This is a question that I have been asking myself for awhile now, to be honest I think they are to some degree. As a developer I value my work as much as the next developer, as well as anything that I may release to potential customers. But to have a larger company come along and just tune out rip off after rip off, of existing games is getting a bit out of control.
My first experience was with GameLoft itself, they released their popular version of Uno & Friends onto the Windows 8 Store, within minutes of me playing I no longer saw a need to play it any more. Due to a small glitch in the game, it was and still is today, to cheat and get all the power ups at no cost to you. I figured I would do the right thing and report the issue to them, since then the game has had one update and the issue has not been addressed.
