Because I'm sick of them shitting on the series. Code Veronica was the last good game in the series. I dont really count the Outbreaks, because they weren't canon. Gaiden was stupid. While RE4 was good, it deviated way too much from what made RE, well, RE. I wont lie, it looks promising, but if it's just shit with glitter thrown on it, then to hell with it. I'm not going to keep supporting Capcom with money that I work for and not be satisfied with the end result. Also, this game will influence future storylines, I don't know why you said it wouldn't. Look how four inspired the trash that was five. Wesker children? Really?
The original influenced the second and third, the second influenced CV, so it's a bit silly to say otherwise.
