There were lots of reports that Elon asked people to print out code and bring it to Tesla engineers for review. They’re Rumors and pretty easy to find. Wrapped up in the whirlwind of news from the last 24 hours was that LOC was a metric used. Also rumored was that Elon asked that his name not be included on any negative memo (presumably out of negative publicity?).
So no I can’t get a citation, and everything is rumors but they’re laying off 3500 people so prepare for lots of rumors floating around.
Firstly: please note that companies have no obligation to reveal this information, and therefore will not.
Secondly: If a manager under Musk made this decision, Musk is responsible as well, unless he renounces it and holds the people who made this decision accountable.
