We now actually have confirmation rent isn't being paid at Twitter HQ (previous headlines mistook a different SF office where rent wasn't being paid for HQ). HQ is where Elon himself works.
I cannot for the life of me understand how the landlord is resisting the temptation to physically have Elon Musk, second richest man in the world, thrown out of their building in front of news cameras.
