As a Canadian, what the heck has happened with MAGA recently?

There apparently has been some controversies and basically a "MAGA civil war" on X / Twitter about H1-B visas and Elon Musk apparently has been going crazy and suspending accounts that aren't on his side. He even used a fake account to go on a Space with some conservatives and he argued with them and even accidentally revealed that he pays several billions on taxes. What random neocon supporting alt account would casually have billions laying around and also sound exactly like Elon Musk?
