Not Meta but I once got yelled at not by a real manager, but by a PM because I said I wouldn't let the team do something shady without legal signing off. I'm in Europe so it was GDPR related.
The PM tried shopping the task to other teams, but nobody took the bait after I raised it publicly, and both legal and the external law firm sided with me after about three months of delay.
In the meantime I raised the topic of yelling with HR but every step of the way the company made me feel like I was the one in the wrong for not complying.
I believe if I were meeker I would probably have complied right there.
