It's embarrassing to watch a CEO of anything fire off what they think are 'pithy' and 'clever' tweets. It's pathetic when Musk does it and it's no better here.
Doesn't he have something better to do with his time as the CEO of YCombinator?
Edit: To be clear, I don't care about the content of the tweets, I'm not taking a position on Tan's politics. I just can't fathom him spending time on this stuff.
