When you register, Twitter/X asks you to follow a popular account. He is one of then. The problem is that maybe those accounts are used once to see Twitter content and then forgotten. They could be used to login in a different website. I don’t doubt that he has many bots following him, but inactive bots are useless.
He’s that bad at business. On Twitter, Musk has no workers to contain his bullshit or create a good public image for him. Nor does he have enough workers to keep Twitter running smoothly as it used to.
