I am troubled by this one:
does the copycat had the authorization to copy the original and put it on store ?
If not, then it's a shame, no matter what were the 'public reasons' given by the author to remove his game from the store, he may have had other (private) reasons to do so.
Yet it's a great opportunity which many of us hadn't thought of.
This kind of game is very fast to do, and as long as the store allow it and original author doesn't say anything, it's a win \o/
