The concept, no; however, freedom of speech also covers Facebook's freedom to not provide a platform if they choose to do so.

You cannot make me say, write, or publish something I don't agree with; freedom of speech is also the freedom to NOT speak. This extends to individuals and platforms both.

In WW2, newspapers were controlled by the invaders; they were told what to publish, even if the people behind it disagreed.

This confounds the difference between a platform and a publisher. If you chose what to publish, you're a publisher. That means you chose to speak, or not to.

A platform does not chose, but merely let's people speak -- or if it doesn't it interferes with free speech.
