The most frustrating part is not that he would say those things, but that he would now post it publicly. It almost feels like he is bragging. "Look, Microsoft engineers want to be at my company! Look, I am talking down to them and turning them away!"
Not only that but there's this subtext that's screaming out "Startups are cool, right? Startups are cool, right? This is worth it, right? I'm cool because I'm part of a startup, right? If I speak condescendingly in blog posts itll seem like I'm successful and awesome, right?". I don't know this guy so I shouldn't pass judgement. I'm just saying that's how it comes off. I'm sure he's a nice guy otherwise.
