The former head of the SC team that wouldn't downsize called the 500 person layoff "literally the entire team" and then there were multiple reports that Elon cut the entire team due to the manager not laying off individuals.
There were also employees, that were laid off saying;
The Supercharger team was well-staffed, they struggled to handle all the workload and that he had to be available 19 to 24 hours per day.
“We couldn’t keep up. And now
the network is even larger,” the employee said. “Now, guess what? There are even more consumers. There’s gonna be a lot more issues that could possibly come up.”
or all of the quotes posted about new sites being paused, permits, etc.
This was by every single bit of evidence exactly as the employees who were fired described as "the entire Super Charger team".
I thought you were joking still talking about this.
Now, obviously Tesla has given the SC tasks to other departments in the form of skeleton crew, but there's 0 reason to dispute this. Elon isn't disputing it, nor are former employees.
It could absolutely be for the best, but it will take time to see. It's not worth panicking over, but also odd to try to defend as "it's not a significant portion of the team" a leap completely made up by you.
