If you hate the practice of exclusivity (or the version of it that Microsoft or Sony have these days), the more effective action would be not only to not buy it but also to not play it. When you play it, you can discuss it on forums, share word of mouth, and other things that encourage other people to buy it. When you don't play it, you're probably supporting some other game that needs the support more and abides by your values.
