You're describing the legal standard of free speech, vs the terms of service laid out by a corporate. As a private company, Twitter is presumably free to draw a line and enforce it consistently. I'm sure it's a fine line to walk. But, saying you have to allow Nazi propaganda because you allow pornography is a false equivalence. There are plenty of illegal/objectionable forms of pornography, which I purposefully did not include. Deciding you are not going to filter any content regardless of imminent lawless action seems especially reckless. I'm sure we'll be seeing this play out in court over the next few years.
