It may not be any different. In any case, and irrespective of this specific case or how anyone might feel about it, I think it's probably a good idea to be critical of claims like bad cultural fit when coming from corporate execs. Yes, there are some people who are unable to act in a way that most would agree is a professional manner, and indeed these people are toxic and pretty much impossible to work with, however, I have a strong suspicion that bad "cultural fit" in many cases is probably just an instance of bias and essentially a weasel term to make it acceptable to only want to hire people of specific demographics.

At this point I really wish tech would just abandon this whole "culture" thing were the company hopes to be a center of social activity and just go back to being a place people work and get a paycheck in return.

If I brought my employer bad press or just made myself enough of a bother with complaints about their tabs vs. spaces dictate I could be fired.

Yea but Google isn't firing him for "lack of cultural fit." They're firing him because they don't like it. Big difference.
