They're willing to work under the current snake, even got him back after he was removed, so why not musk?

They are both snakes (IMO), but they are different kinds of snakes. I can see why to some Sam is acceptable while Elon wouldn’t be (and vice versa). It’s also convenient to be more lenient toward the snake’s shortcomings when you becoming extremely rich depends on it.

Haven't they hemorrhaged a lot of the founding talent in the years since? Now it is full of ex-Meta ad-tech people trying to find a way to make it actually turn a profit.
