I don't see any evidence of coordination or organization. Rather they all saw a dangerously out-of-control situation where they could be found liable, or at least involved (in the court of public opinion) in armed insurrection. They all demanded some form of the same thing: moderate the dangerous conversations that were calling for rebellion and violence. But they did not demand a particular methodology (which you would have seen in an organized endeavor).

If your service suddenly becomes synonymous with an armed uprising, and your response is to talk about free speech and how it is not your fault... then ya, you are going to loose business partners left and right.
