It’s pretty simple, actually. Once such a dominant market position is achieved, you can get away with almost anything, whether with customers or employees. This is true of all the BigTech companies.
I think there's more to it. When you're dominant, you make money whatever. Think of Amazon et al. as huge spigots of money. Now, it becomes optimal to fight for more of that money coming your way. It's like the resource curse for countries. Nobody gains from growing the pie; they gain from stealing the pie. At some point, parasites and parasitic behaviours invade.
