If you mean “proof”, then lol. Off the top of my head:
- the pedo guy moment
- the hyperloop smoke and mirrors which are actually just his campaign against public transport
- the several union busting episodes
- the whole “Tesla is going to save the world” thing
- the multiple harassment cases
- the multiple instances of overwork, discrimination, and general lack of any consideration for his staff
- all the severance payments he failed to make after having fired a whole bunch of people
- the stupid ultimatum before one of the firing episodes, plus the utterly stupid “show your work” thing that came just after
- the multiple times he stiffed his creditors (either landlords, lawyers, contractors in general) or tried to do it
- the way he tried to force open Tesla factories in the middle of the COVID pandemic
- the multiple instances of pushing Russian propaganda verbatim (concerning.)
- most of the Neuralink saga
- the FSD vapourware that has been coming next year for a decade
- the way he publicly disparaged people who were killed by their Tesla using telemetric data that are supposed to be confidential
- the Media Matters lawsuit
Well, I could go on. He’d need to work quite hard to reverse his public image of massive arsehole at this point.
