Your average Joe didn't know who Mike Lindell was until a couple of years ago either (even with his ads on news channels). Among a certain crowd, Musk is being hailed as a champion of free speech and a warrior against cancel culture. These are not Tesla drivers.

I still have no clue who Mike Lindell is

I'll spoil this pleasure for you: he's a guy who sells pillows online and vocally supports Trump. Seems quite unhinged, possibly related to his long-term drug abuse and eventual religious conversion.
