it is not his role to evaluate the release or the the communication, or the developers personality, he has to judge the game, so he doesn't have the freedom of you forum posters to just vent his feelings on those things.
And this is where I am absolutely convinced you are wrong. Following that logic further, you might as well buy products from baby-seal-slaughtering-nazi-communist-homophobic-fanatics, because the product is just good. Who cares whose pockets we fill, eh?
I know Crafty Studios is not that kind of evil, but if a logic is not working at extremes, it is probably not working too well at all.
A purchase, especially when you have the choice to not do the purchase, is always a statement of some sort. It may be the statement of "I don't give a shit, just gimme dat thing". But everyone knows that buying the product will support the creators (usually, certainly in this case).
Therefore, by telling people that this is a game worth buying, you do not only say "This is a good game". You also say "The devs should be supported". And after what those guys pulled off, I can only raise my biggest WTF-brows to anyone claiming that Crafty Studios is worthy of support, as that basically says "What they did is totally fine. Encourage them!".
This is, IMO, after thinking about it some more, what brings up all the rage. A good rating for a game is always also a good rating for the developers. And who would ever give Crafty Studios a 3/5? Maybe the reviewer. But I (and many others) can only strongly disagree.
I don't claim the game will never be good. Who knows? I just claim the developer should not be supported for this game. Maybe on their next. Who knows…
Also, that whole claim of objectivity in game reviews is nonsense. There cannot be a fully objective review of pretty much anything, even less for products that involve some kind of art/design. Not that anyone ever claimed this review to be fully neutral. This is more a general statement.
