Musk isn't some young kid but a 49 year old. 2 years ago he baselessly accused a rescue diver as a pedophile and doubled down on it in court. For some reason, I doubt Steve Jobs would have done that. I don't know what "kind of personality" this is but if you have that kind of personality (CEO or not), yes, stay away from Twitter and all social media. Though that wouldn't be your biggest problem anyways.
For what it's worth, Musk's defense on that one is that, where he grew up, "pedo guy" was generally used as an insult not to be taken literally, any more than "idiot" seriously means "IQ between 0 and 25". He does seem to be telling the truth on that one; his judgment is questionable on multiple counts, but it's not a case of deliberately making up an accusation.
"Elon Musk is right, it seems: in the 1980s the phrase "pedo guy" was used as an insult in Pretoria, where he grew up – and it was a generic reference that did not necessarily mean someone was a pedophile. But telling a court in the United States that the slang was "common" in South Africa may be stretching the truth, according to other people's recollections."
He did then hire a private investigator, who apparently produced some suggestive reports: "that Unsworth had met his wife when she was eleven or twelve, and that he had been unpopular in the cave rescue team because he was "creepy"". Apparently on the basis of this, Musk made further accustions in a later email to a third party—one prefaced "off the record", but that wasn't legally binding:
"“I suggest that you call people you know in Thailand, find out what’s actually going on and stop defending child rapists, you fucking asshole,” Musk wrote in the email, according to BuzzFeed News. “He’s an old, single white guy from England who’s been traveling to or living in Thailand for 30 to 40 years, mostly Pattaya Beach, until moving to Chiang Rai for a child bride who was about 12 years old at the time," the email continued." http://web.archive.org/web/20200605035828/https://www.busine...
Clearly impulsive, and he seems to have leapt to conclusions from the PI's report (I don't know exactly what was in it and how much was Musk reading between the lines) that seem to be false. But at that time, the accusation didn't seem baseless to him.
