Except for all kinds of established laws broken by the state itself (e.g. extrajudicial deportations), or "fast and loose" startups like Uber and AirBnB, or any big enough company really.
And when they can't fit through exceptions to the law, they magically pay politicians and buy their own laws.
But god forbid people can talk freely about it. What if they don't have the right ideas about things?
In particular, see the very first bullet point: Section 230 makes no mention whatsoever of a publisher/platform distinction. People like you appear to have invented this dichotomy out of whole cloth and attached relevance to it which does not actually exist.
Platforms shouldn't be deciding for you what you see, outside of the obvious outright illegal things like CSAM
Anything else is just a slippery slope fallacy
Seems pretty clear to me man
