“Trump should be careful of this though because Musk is mostly out for himself. His purchase of Twitter harmed DJT because he’s been trying to compete with Truth Social for conservative viewers.”
If Musk was only out for himself he would never have bought Twitter.
You are totally wrong about him.
Around the time that Musk bought Twitter, he stated in an on-the-record interview that he wanted Trump to retire and that DeSantis was better. I think he was trying to hurt Trump when he bought Twitter.
That doesn’t mean that he might have changed his objectives since then.
