It's because even though Elon Musk is no right-winger, he voted straight Democrat his entire life until very recently but then he voted for a Republican. The haters will brook no deviation from their accepted political narrative, and when Musk did it the hordes of people with pronouns in their bios turned on him.

For those people it has nothing to do with technology, which is why their takes were so hysterical and wrong. It's 100% about politics every day, 24/7.
