Tech companies have brought this on themselves with their one sided content "moderation". Not that I think this is the solution - I think if a company wants to keep their 230 platform status they should be required to publicize not only their content moderation policies, but also publicly document and reference those policies for all content moderation decisions.
Sunlight is the best disinfectant.
Don't like that? Fine - you're a publisher. Game on.
Great power should require great responsibility - yes, Google, Facebook and the rest are private companies - but they are receiving special benefits via section 230 from the government too.
