It seems to me to be more that a16z just wants to squelch anything that doesn't support their agenda. They are always talking up their latest startup no matter how flimsy it may be. Anything critical said about the regard as hate speech. A place like Hacker News is anathema to them since people here are more often critical and less often buy the hype. Which is why they call it Hater News.
