Workers and customers can sue Tesla too. Workers can also go work elsewhere and customers can go shop elsewhere. No one is forcing anyone to work for Tesla or buy their cars. If you choose to deal with a shit show owned by a lunatic - it's on YOU.
Most workers and customers can't AFFORD to sue Tesla.
As far as your voluntarily buying, a lot of customers have been misled with regards to things like build quality, free features that became very expensive and many other things.
With regards to nobody forcing people to work for Tesla, it's actually damn close: there's no guarantee that they'd be able to find another job that doesn't underpay and mistreat them even more and Texas, where Tesla is based, is one of the many states that treat unemployed people worse than most western countries treat convicted criminals.
Tesla Inc’s directors will return $735m to the company to settle claims they grossly overpaid themselves in one of the largest shareholder settlements of its kind, according to a Monday filing in a Delaware court.
