For whatever reason, I've observed public opinion of Musk to be highly polarized. Some (very strange) people literally worship him, and others seem almost personally affronted by his existence and bend over backwards to ignore and/or explain away his obvious, somewhat unprecedented successes. Since to me they are rather obvious, I tend to take any one-dimensional criticism of his abilities as a technical leader with a grain or two of salt.
I would never want to work for him, but that's not quite the same question.
It used to be mostly just for fun / internet drama for the most part. Like, PS3 vs XBox sorta thing. I take sides but its all just for fun.
At least, it was all just fun internet drama until last year when Elon's COVID19 denials went on 100% full display so that he could keep his Fremont factory open. That pissed me off significantly, so I admit to being angrier today than normal. When I saw him use his "hype" to pretend that he was going to build ventilators for hospitals (with 100% confidence that he was bullshitting everyone again), that just made me angrier. Its no longer just him running a quirky company, he's actively stepping into dangerous territory and explicitly spreading COVID19 conspiracy theories among his fans now to push political ideologies that are convenient for him.
He's playing both sides: COVID19 denials when it keeps his factory open... COVID19 production ("ventilators", which happened to be worthless CPAP machines) to boost his own ego afterwards and help negate the damage. Its pretty annoying. (It is a donation of medical equipment, but it didn't help the COVID19 cause at all)
So that crossed a line for me. I do try to keep things in the "fun XBox vs PS3" kind of debate as much as possible, but I have to admit that the past year has really bothered me with regards to Elon.
So while he's not quite anti-vax, he's spreading the paranoia about the vaccines (and was certainly spreading COVID19 denialism last year 100%, likely in support of his preferred factory politics)
I would never want to work for him, but that's not quite the same question.
