So do you support people manipulating and creating fake news but not the people who are trying to prevent it from happening?

Facebook can absolutely kick out people who don't behave on their platform. Playing the freedom of speech card doesn't work when you actively try to oppress other's freedom of speech through tactical manipulation.

Punishing individuals and groups who willfully and knowingly engage in spreading information containing false facts concocted to support their intolerant views is absolutely necessary to protect freedom of speech.
