In this case, I am fine with the same exact standard being applied to everyone, regardless of which side they are on. Yell 'fire' in a crowded theater, lose your platform. Plot sedition and insurrection, lose your platform.
But I am concerned that this might have been done too ad hoc. In which case, there is no rule or principle governing everyone, and that's not a good thing at all. The scope of the term 'fair' does NOT extend to 'Trump Rules' whereby one person or group is immune to playing by the rules the rest of us must play by. I want the same justification for taking down Parler to apply to taking down any site or service.
