I think any hostility you see is due to his comment of "I'd rather have minecraft not run on win 8 at all than to play along.". He'd never be dumb enough to do this so why say it, and why stir the pot with everyone who thinks Minecraft really really might not run on Windows 8?
Why would he never be dumb enough to do this? It seems that he does not see it as a moral decision, and I'm guessing he's betting that windows 8 adoption will never be that large.
