Tesla's Supercharger team was laid off


Total conjecture here.

Seeing that Tesla was receiving money from the US federal government to increase the charging footprint and knowing just how shady our government is, it is possible Elon made one of his signature F-You's. Who knows what kind of blackmailing-quid-pro-quo our government may have thrown at him?
 
That article does support my pun.

It's a power move that either he's going to walk or every one drops a few more dimes into his pockets.
It could also be that he's seeing a huge potential problem coming up and he doesn't want to deal with letting every single manufacturer have access to his stations.

So, you fire off a team that isn't pulling their salaries right after getting a a proposal that was going to cost more than it provided and headaches from needing to provide 200 different adapters. So, he's walking away until either it pays to deal with the red tape or he's going to sell off his stations.
