I know someone (not an engineer) who was applying to jobs for a long time and got a 100% pay increase from moving to Meta, about $60k -> $120k. In such circumstances, it is difficult to turn down such a job. You are only one small part of the machine and it is such a quality of life increase (in USA), I cannot imagine many people saying no.

Some other common reasons that I disagree with, but are quite defensible:

"Well-targeted advertising is a net positive, or at least not hugely negative, for the world. Better targeting has helped many small businesses succeed where they would otherwise not been able to get customers"

"I am working on account security/React/ML/etc which is a good thing. I don't endorse all the bad things"

"It is more complicated than it seems, and most people at Meta try to do the right thing"

"I might as well work at the company and try to make it better from the inside" (while making lots of money)
