Please take a moment and consider the implications of a nationalized company that tracks and records every thought of its users.
Quite frequently, yes to both questions. Choice is key and many often feel more empowered to individually choose their company than their government.
When there isn't meaningful competition in a market, it's specious to point to the abstract possibility of competition as an argument for sucking it up and cozying up to the monopolist, who has structured your arrangement with them to limit your freedom and recourse as much as practicable.
A profit motive doesn't magically make the human foibles that the "Gubmint is baaad" crowd insists will lead to the end of human freedom — and puppies, too — more manageable, or less dangerous to the rest of us.
Oversight. If you want meaningful competition and don't have it due to harmful monopolization, that's the government's problem to solve. Nobody's asking for self-regulating companies here. It's very important to understand which forces can or cannot actually eliminate competition and choice. If there is a path towards choice, I'll take it. Often that path is unclear of course.
How's that working out for us?
Maybe my premises and categories blind me to that risk in some way; I'll certainly cede that possibility. I'd be curious to see people who think the way you're describing do the same, vis à vis theirs.
That's the trouble with articles of faith, though: for the people who hold them, they're axioms; for the rest of us, they're implicit, unsupported premises to someone else's argument.
