Don't you think those companies are mostly correcting for their massive covid overhiring + zero rate bonanza coming to its end?
Also, back when elon had bought twitter and had been firing people left and right, it was prophesied that with such inept management the company was going to collapse very soon. I thought it was obvious it would collapse. But that has not happened (yet, but it's been quite some years), and the service seems to be holding up after some initial shakiness.
