Elon Musk infamously paid $44 billion to purchase Twitter, and on Tuesday, his pricey platform was promoting a hashtag dedicated to eviscerating him over his decision to deny the Ukraine military access to Starlink over Russian-occupied Crimea.
He can't care less. They're still engaging with the platform and generating ad revenue. Maybe don't protest a platform by continuing to use said platform and therefore making it money.
I honestly wouldn't be suprised if the engineers screen the tweets before showing them in his feed or else he would constantly be forcing them to "fix" the fact people are tweeting mean things about it.
