I understand that, but companies are trying to have it two ways. They're either curators and editors and somehow responsible for the speech on their sites, it their carriers and just providing a forum. If Reddit isn't responsible when people post libel or legally actionable threats, then they shouldn't be taking responsibility for policing their content for ideological alignment, much less politeness and courtesy. I'm saying it's time to explore whether we need common carriers of speech like we have for raw data.
