That's quite a stretch for justifying garden-variety flamebait.
As it turns out, you're wrong on the facts as well. YC got out of China years ago. But none of that ever had anything whatsoever to do with how we moderate HN. It's much more straightforward: we don't want predictable, tedious, nasty flamewars on HN, we want the opposite.
That's literally all there is to this, even though I routinely get accused of being a secret agent, stealth activist, or some other sinister entity just for doing this silly job. The only non-obvious mechanism at work here, indeed the sole aspect that isn't brain-dead in its obviousness, is continually trying to figure out new ways to explain this to the community.
