The content creators freedom to express directly opposes the hosts freedom of affiliation. Not that I want to defend either company but they do have the right to say what is and is not allowed in their spaces using the same idea of “fundamental human rights”.
It is either that or we have to agree that “fundamental human rights” cannot exist because one groups rights can override the other on social whim.
Every other creator on the planet has to abide by these rules if they want to remain on these platforms and every creator has an option not to use them.
