Where's the government in this? The government isn't forcing Facebook's hand.

The government can be forcing Facebook's hand by making Facebook fearful of being investigated, fined, broken up, etc if they are found to have allowed manipulation of the 2020 election in any way, and the coronavirus and related topics have become unfortunately intertwined in that.

Huh? If any forcing is going on -- which there isn't -- they would presumably be forced to toe the Trump party line, not to suppress or censor it. Wouldn't the present Federal government be happy if Facebook were to encourage protests and general disrespect for warnings from health authorities? If anything, Facebook's actions here are courageous.

It takes a lot to get me to defend Facebook, but the arguments popping up in this thread are proving to be more than sufficient.

Well, the official Trump party line is indeed that social distancing and other restrictions are still necessary. This is a very confusing situation since the protesters against the protective measures seem to be almost exclusively from Trump's base.

And forcing Facebook to publish points of view they disagree with doesn't harm the Bill of Rights?

Of course not. Facebook is a corporation; people are what have rights.

As assemblies of people, corporations have rights. In fact, the right of the people to peaceably assemble and petition the Government for redress of grievances is explicitly protected in the First Amendment of the Constitution.

So Facebook is an organization of what, robots?

Are you OK with similar rights being stripped from your hometown newspaper on the grounds that they are a "corporation", despite the explicit specification of the press as a protected entity in the First Amendment?

In America, corporations are people.

Citizens United v. FEC

This doesn't mean what you think it means. Not all rights that attach to people attach to corporations. The bill of rights doesn't uniformly apply to corporations, and different rights may or may not attach under certain circumstances.

More importantly, the government declaring something doesn't make true. See anything from the entire Soviet Union to the various attempts to legislate that π = 3.
