No, I do not have this game, and I probably won't be buying it either.
All the more power to you for not buying a game in principle, if you're into that kind of thing.
Basically the only things you need to ask yourself is this:
-Does the game look like it could be fun for me?/Will it entertain me?
-Am I prepared to spend the money needed to buy this piece of entertainment?
Whoever made it and whatever the reason would be for the increase in price is beside the point. If the man you hate made a good piece of entertainment, why would you deprive yourself of entertainment just because one of the guys behind it looked at you funny in the metaphorical sense?
Also yes: Increase in costs to benefit developers/publishers are a *****, and there's probably some ethical ambiguity to be found behind it. Still if you can afford it and you want it then just get it. Like you said it won't have any effect on the big picture, and you'll probably be fueling the fire, but do keep in mind that if these price hikes go too far no one will stand for them, which means the people who screwed you over will be getting screwed by themselves and their greed.
Then again if it makes you feel better to not buy the game for the reasons you've presented than actually enjoying the game, by all means stay your course.
