>In retrospect, I realize that a lot of tiny acquired startups don’t know what the fuck they’re doing and so the behemoth just gets used to assuming that everyone is like that. Just grit your teeth and take it.

This, I'm not sure if this should even be considered a negative. Too often start-ups and smaller tech companies try to reinvent the wheel and call themselves 'agile' or whatever. As a contractor I'd almost always rather deal with a large company - if for nothing other than a dedicated payroll dept.
