It's also the American conception of free speech, which culturally differs from most countries. In the US, if a private company censors arbitrarily, it's still freedom of speech because you're still allowed to build your own competing business, and anyway it's your fault for agreeing to the legal terms and conditions. Even if it's a monopoly, Americans view freedom as something only governments remove.
