I think what happens is that there's usually 1 in 20 people who can't take honest feedback face to face. In the worst companies or the "top" ones, the ratio is much lower - I'd bet in some major bank, a unicorn, or a FAANG somewhere, there's a lot more egos. And more people who are the type to gaslight you and say your feedback is invalid, or get really defensive and make excuses for everything.

But in a large enough companies, where people in different departments don't talk to each other, this can be toxic.
