>Eh, I disagree that it's childish advice! It works out pretty well for everyone except the person being frozen out

then that person posts on hacker news why no one seems to want to "be an adult" , how they are blocked on tasks due to slow communication, and overall feel the workplace is hostile.

And the chain of apathy continues. And people wonder why work is so miserable. PAy can be a factor, but it usually isn't in tech.
