Musk is suspecting plots to sabotage Twitter from disgruntle employees, and has closed whole office buildings, asking employees to meeting on an upper floor.
If you think about it, given the extreme liberal bias that Twitter has shown, and Elon’s stated preference for “free speech absolutism” it is a real threat.
In fact this could be an existential threat. He has already called in tech staff from Tesla to help out. I’m very sure that he will still have issues.
Some crazy-assed liberal will stay behind to sabotage Twitter.
