Nobody is talking about free speech as a matter of constitutional law in these instances (although even that applies to more than the federal government, i.e. state and local governments.) People are making a normative claim that it’s better for institutions like YouTube to have liberal speech policies than restrictive ones. If you want an example with opposite political valence think of NFL players kneeling during the national anthem. The NFL can legally punish players for exercising their constitutionally guaranteed rights, but it nevertheless has a chilling effect.
