Won’t one party always have restricted freedom of expression in this situation? The private company wants to express themselves freely by curating the content on their social media platform. The individuals wants to express themselves by posting material of themselves with less clothes than the company wants. These both seem to me as entities wanting to express themselves freely. Which freedom are you most willing to limit?
And if you argue that the freedom of an individual should be valued more than the freedom of a private company, should individual people owning websites have their freedom of curation/expression limited?
