I think you'd be surprised by how many people don't really engage in outside-of-work anonymous programming forums, vs their personal contacts/friends/coworkers/ex-coworkers.
The handful of Reddit programming communities I've seen are also very uninterested in returning to work. I have to wonder if the difference isn't so much "established career" vs "newbie" and is more simply self-selection, with people who are comfortable working remotely more likely to engage frequently in online communities, and those more interested in in-person work less represented.
Also anyone who has been earning a FAANG salary for 5-10 years should have enough FU money to feel a lot less pressure to conform to unreasonable employer demands.
There is a really funny one where the guy goes back to work and hits his head on a door.
