Except he tries justifying it.

"Github’s servers are constantly on fire as their usage increased something like 50x due to LLM sloppers pushing large amounts of trash code"

"Unless you have a emergency hotfix (you don’t), go hit the gym or walk outside." with assumptions like above.

If it was, "hey they f*ed up but there's no point having an overly emotional reaction" that would be fine. But he seems to be justifying this. Especially with Github's record up to now of unreliability I think it's completely fair to be annoyed.
