It's actually not surprising if you follow YC and HN for any length of time. The prevailing tone coming from sama, pg, and the mods at HN is that:
- They and they alone are in a position to speak on behalf of all of "Silicon Valley". - They are above the law (see for example all of the mental backflips and excuses given regarding AirBnB's clear-cut and widespread facilitation of lawbreaking).
You can see this arrogance peeking out here and there, such as the now-deleted statement you highlighted (side note: isn't it also incredibly arrogant to think that they can simply delete things from the internet and pretend they never said them?). It feels like it's been happening more and more lately. I expect that in the absence of any kind of reality check, it will continue to come out more and more.
