The problem is that mobile has accustomed its users to the free/99 cents model. If you are a developer on mobile you'd be blind to not understand that. Heck, I myself wait for a Deal of the Day now because games I've paid $5 bucks for end up free or 99 cents at some point. Its about time devs tell Apple and Google to do something.
Pretty much I'd say the same reaction would occur if Steam went a year without sales, or decided something like "This Winter the only games on sale will be indies" or something to that extent.
You've accustomed your consumers to a certain standard and its the kind of consumer culture Apple and Google have created for their shops. Its going to take a lot of work on both Google and Apple to change that culture which they don't seem to care about doing anyway. They can tell devs to create meatier and costlier games, but if the Ripoff Artists that plague mobile shops can create the same game with a different skin, sell it for 99 cents and Apple/Google lets them do it, the "entitled/casual gamers" on mobile are going to continue existing.
