Sorry, I was mistaken on the bootstrap comment - UI Bootstrap is separate from Angular and has little affiliation with Google other than the creator of the project being a part of the core Angular team.

I can't speak to the online interactions as to the comments, but I do recall the comments being outdated and not useful in a bunch of cases.

The Angular team is very professional and pleasant to interact with in my experience though. Igor once told me that open source is hard - I was skeptical at first, but being in charge of a major project myself now, I wholeheartedly agree. It is challenging to keep development going at a good clip, manage the team, and satisfy developers using the product, who are a ruthless bunch.
