I can certainly see a lot of parallels with Oculus / Facebook.
Perhaps unusually, I actually wanted FB to impress itself more strongly on Oculus post acquisition because, frankly, Oculus was a bit of a mess. Instead, Oculus was given an enormous amount of freedom for many years.
Personally, nobody ever told me what to do, even though I was willing to "shut up and soldier" if necessary -- they bought that capability! Conversely, I couldn't tell anyone what to do from my position; the important shots were always called when I wasn't around. Some of that was on me for not being willing to relocate to HQ, but a lot of it was built into early Oculus DNA.
I could only lead by example and argument, and the arguments only took on weight after years of evidence accumulated. I could have taken a more traditional management position, but I would have hated it, so that's also on me. The political dynamics never quite aligned with an optimal set of leadership personalities and beliefs where I would have had the best leverage, but there was progress, and I am reasonably happy and effective as a part time consultant today, seven years later.
Talking about "entitled workers" almost certainly derails the conversation. Perhaps a less charged framing that still captures some of the matter is the mixing of people who Really Care about their work with the Just A Job crowd. The wealth of the mega corps does allow most goals to be accomplished, at great expense, with Just A Job workers, but people that have experienced being embedded with Really Care workers are going to be appalled at the relative effectiveness.
The communication culture does tend a bit passive-aggressive for my taste, but I can see why it evolves that way in large organizations. I've only been officially dinged by HR once for insensitive language in a post, but a few people have reached out privately with some gentle suggestions about better communication.
All in all, not a perfect fairy tale outcome, but I still consider taking the acquisition offer as the correct thing for the company in hindsight.
