People can whine, make petitions, rant on youtube videos, but Square Enix (nor any of the suits in any corporate companies) don't care.
If you don't like 3rd party game exclusitivity deals (and you feel cheated that a game that you've supported on previous gens on PS consoles are going to another console), DON'T BUY THE GAME when this is released later for the PS conosoles. If the sales are low, then they'll listen.
