Andrew's online social behavior is largely a streak of pettiness imo. This is not even close to the first time I've seen him write something I felt was overtly mean spirited, not just euphemistically "blunt".

"Was silence not an option?"

i watched a youtube video where he called out people as garbage programmers... i felt that was petty, his streak continues i guess

Given the chronology set out by Andrew, I think it's warranted anyway.
