He basically stopped working, and when asked why stay and take the huge salary from google when he's not working he said he's satisfied with the salary, and he was given plenty of opportunities. No wonder his managers didn't like him. There are tons of other more competent people who make the same salary as him working hard. It's not a matter of whether the company treats people like a "resource" or not. If I had a guy on my team who doesn't work at all and sticks around AND is proud of it for some reason I would be pissed. I'm sure not just his manager but all other colleagues probably would have been super pissed if he acted like he described in the answer.
For some reason everyone on the thread is talking like Google is in the wrong and he's being noble for sharing it non-anonymously, but I don't really get what's so noble about this. If I was that burned out, I would have asked for a hiatus. And even after that if I can't focus, I would still try hard, and when asked why I don't just leave, I would take that as a sign and leave. I would definitely not say "I'm happy with my Google salary". Normal people don't feel OK with taking someone else's money while not doing anything, and "being burned out" is not an excuse.
