Musk decided that this is not what he voted for, nor what he supported and is now clearly playing with the idea of creating a rival party.
Musk also decided Bitcoin was dangerous to the environment, so he ceased Tesla from accepting BTC as payment method, causing a major crash in Bitcoin market years ago. He also decided to promote Shiba Inu through enigmatic and subliminal tweets, although after a while he claimed to have never promoted the token.
This guy is constantly deciding contradicting things along the time. It means he is just a manipulator playing with the masses. He knew who Trump was and how he was going to act, but it was interesting for Musk to support Trump back then, so he could act like he is doing right now. It's a game of premeditated actions and decisions.
A decaying USA commanded by Trump is what Musk needs to shine as a brand new leader.
Except for one thing. Musk in all his moves is fighting the Deep State one way or another.
