Well get back to me when you've worked out exactly when a private entity shouldn't be able to decide what content they allow. This ambiguity is really too difficult to figure out.
Like I said, banning illegal content is the first step that anyone ought to take. Generally this is done via moderation staff of the site + user submitted reports. If you're providing a free platform and terrorists start using it as their communication channel, then you're only at legal risk if you do nothing to stop them. However, I'm imagining things like the NZ shooter's 8chan post, where a direct threat is made or a direct implication of violent acts to come. Posting a "terrorist cookbook" actually is a good example, as its sort of right on the line. It seems to be the sort of information that only has negative uses, on the other hand its just information, as opposed to an actual threat. I'm not really sure if such things should be allowed... it could be helpful to terrorists which is bad, but also censoring information is nearly impossible and almost always seems the wrong way to go.
>Does Zuckerberg have to come to their house and load the bullets into the gun for them so they can make a statement about how angry they are? Because he made an app for people to cheat? I fail to see the connection.
As do I...I really don't get what you're trying to say here, can you restate?
