Censorship in the modern context typically just means discouraging a particular type of tool or specific tool trait. Platforms like Facebook, Reddit, and Twitter are just social tools that are in a persistent stage of development after all. And given their broad use cases I'd argue they're some of the most versatile tools in history behind simple machines and electricity. The same could even be said of previous social tools like the telephone and the radio. Not that no regulation is good either, but it seemed worth pointing out since it's unclear to me why you're making a distinction between social tools and other types of tools.
