Layoffs to service are going to be felt a lot quicker than anything from the supercharger team. Tesla service was already backed up when I had my Model Y. Can't imagine it getting worse.
I'm fine with not having payment screens. I wouldn't be surprised if a good portion of EA's issues stem from having to support the massive slow payment screen. Rivian and Ford already support plug and charge for Tesla superchargers, no reason other manufacturers can't do the same.
Tesla sales...
As long as demand for Foundation Series outpaces supply, they will keep building them. I doubt even Tesla knows how long it will be before they switch to standard.
