I'd be pissed if I put in a lot of effort revising my contributions to a project, only to be told at the end that "I like my version better, so go away!". This is not how a project reliant on community efforts could sustain itself.

I always thought a project as big and respected as that of the linux-kernel would have folks who know better, and look out for the best interests of teh project while respecting new-comers. After all they were new when they started contributing?

I dont think anybody in their right mind would advocate for a "not best" solution to be accepted just because a new-comer brought it. The right thing to do would have been - "Here, I have reviewed your patch. This and This are troubling because of this reason. I'd recommend re-writing this like that. Tell me if you need assistance with this, and I can help write that part" and co-author such a patch. That's how you get a good pipeline of future contributors who also care.
