>This, on the other hand, feels bitter. It seems to be coming from a place of hate.

Of course is bitter. Dude said it clearly. Was hired as WFH before COVID, had challenging work, enjoyed it and then some asshole higher up, one day, decided to RTO indiscriminately for everyone.

And I didn't felt any hate, just disappointment. He was disappointed that he had to resign. Hence his rant. I would rant too in same shoes.
