You miss my point completely and i am unsure how to reword it.
Yes they are exclusively big players already, thats why it wont work through top down regulation and requires user action.
We might be better off without them, but i dont see how that could ever happen through top down regulation. The economic and political incentives are way to strong and bureaucracies way to unwilling and incompetent. You cant destroy such profitable business models through regulation, they have to much pull here. At best you get regulatory capture. It will be another iteration of "safe/privacy on paper" allowing for higher profits and more entrenched monopolies for said megacorps.
Intention is not a valid metric, outcome is.
