He was fired
He owns the business. His ownership was liquidated by the other owner without paperwork, and most of the other owners dispute that the ownership was ever diluted. The decision over whether he should have been "fired" are really upto him and the other business owners.
It's also unclear why the other employees, who may or may not have been coerced, were not siding with Kurvitz. I agree it's a mess, but there's a big gap between "feelings" and "actually grossly illegal stuff".
Not a premium user but Youtube has poisoned its own waters with its algorithm. You can see the "top" content basically gaming that algorithm as well as it can. Literally every part of it from the title to the thumbnail to the content itself is hollow except for the skinner box.
