Assuming they regularly use the English-language internet, I feel like it's less they don't keep up with it and more they're willfully blind to it. They would have to either go out of their way to avoid it or assume every article that casts him in a bad light is from jealous competitors in industries he's iNnOvAtInG in.

I don't give a shit about Musk at all and have never actually seeked out news about him yet it's basically impossible to not see headlines about his latest bullshit antic if you're just casually on the English speaking internet, so I really doubt there are that many people who are just "out of the loop" unless they're not a native English speaker or rarely use the internet at all.
