If so then yes I agree. Government censorship is unacceptable. But that's not really comparable to private entities censoring on their own private whims.
In what way is Facebook at all comparable to a government? Is there some social contract that all people are entered into with Facebook? If so, what are the rights and responsibilities of that contract? And do note here, I'm talking about an implied social contract, not an actual contract (like an EULA).
What large portion of the internet do they "govern"? As best as I can tell you're arguing that any sufficiently large entity is essentially a government. That's ridiculous. So please, please explain what you do mean.
They have written community rules (don't know the exact name) that members are expected to comply with.

The Facebook website (duh). Which, for a surprising amount of people, is literally "the internet" (or at least the part of it that they most interact with).

No. For instance, Toyota is not a government because it does not set rules under which I can use their cars. Facebook does set rules under which I can use their platform, and it enforces them (which is the entire point of the submission). Setting rules and enforcing them is governance.
In fact, every moderator on any public forum is in the governance business. Since Facebook is so large, I find it reasonable to liken it to a government in terms of influence of its governance.
Just to be clear, this definition also makes Walmart the government of all Walmart stores, and me the government of my bedroom. Neither of those are in any way related to how the President is (a part of) the government of the United States.
[1] Edit: Within the boundaries of the law. But if that were a problem with your definition of "governance", then state governments (which operate within the boundaries of federal law) would not be governing either.
And to be clear, what we mean by "fake news" are stories that are demonstrably false with incorrect information that's never corrected even when it's revealed to be false. We're _not_ talking about what Trump calls "fake news," by which he means any narrative that doesn't paint him in a positive light.
Irrelevant. Limiting speech doesn't solve that contradiction, it only guarantees the worse outcome. More speech solves your proposed "contradiction" just fine.
