The government has a well-established right to request companies to do things, and there are good reasons to keep it.
For example, the government has immense resources to detect fraud, CSAM, foreign intelligence attacks, and so on.
It is good, actually, that the government can notify employers that one of their employees is a suspected foreign asset and request they do not work on sensitive technologies.
It is good, actually, that the government can notify a social media platform that there are terrorist cells spreading graphic beheading videos and request they get taken down.
It's also good that in the vast majority cases, the platforms are literally allowed to reply with "go fuck yourself!"
The high firewall is already present, it's called the First Amendment and the platforms' unquestioned right to say "nope," as they do literally hundreds of times per day.
None of it de facto prevents anything, but if a corporation feels they're being bullied in this way they can sue.
In the Biden admin, multiple lawsuits (interestingly none launched by the allegedly coerced parties) revealed no evidence of such mechanics at play.
In the Trump admin, the FCC Commissioner and POTUS have pretty much explicitly tied content moderation decisions to unrelated enforcement decisions.
Definitely there's possibility for an admin to land in the middle (actually coercive, but not stupid enough to do it on Truth Social), and in those scenarios we rely on the companies to defend themselves.
The idea that government should be categorically disallowed from communicating and expressing preferences is functionally absurd.
