The latter often leverages the former to work around having to legislate things that are unpopular or unconstitutional. A great example is government agencies buying data from data brokers or the Twitter files where the government leaned on Twitter to downrank "wrong" ideas. With the proliferation of powerful near-monopolies - especially in tech - "the market" has little way to work around these kinds of problems, especially in the short term.

I guess my point is that both are dangerous to freedom, and ideally the government would do something to curtail corporate censorship instead of encouraging it. That's the whole idea of a "common carrier"[1].
