Ex-Intel engineer here that worked in R&D- I saw the exact same situations during my time and was one of the reasons I left. The way that teams in the same org with the same goals couldn't or wouldn't work together was incredibly frustrating and such a massive waste of effort. At the time I thought it was a unique situation with our group, but it's sad to see that it's more of a systemic issue that still hasn't been corrected.
There are the opposites as well, I've seen companies that would send you home for even a hint of ego. Essentially "I" was forbidden as it is not in the "TEAM". I much prefer "we" culture than "I" though.
