Having had some back-channel status updates after I got pushed aside, the lesson is that some people accept or discard ideas based on employment background.
On the team I was on, newly-hired managers from Amazon accepted the ideas of ICs who had previously worked at Amazon, and rejected ideas from people who had not. I didn't realize this was a pattern until I already had one foot out the door, but even if I had realized it earlier it wouldn't have helped. I was ex-Google, so the ex-Amazon folks tagged every document with the bozo bit before they'd even opened it.
My takeaway was to be cautious of companies where the culture is imported through mass hiring from single companies. I joined in the middle of the "Google wave", which was relatively peaceful (per Google's culture at the time). When the "Amazon wave" arrived it was quite a shock; their culture was much more adversarial and authoritarian than anywhere I'd worked before. By the time I left, there were signs the Amazon folks were starting to get sidelined by an emerging "Oracle wave".
