Something is being missed in these "Element isn't Parler because..." comments. Distinctions about client vs platform do not matter _at all_ to someone at Google headquarters. Content they find unacceptable is accessible, or it's not. Full stop.
The FAANGs now have a strong incentive to boot anything and anyone making objectionable content available in any way because that's the way public sentiment has shifted. It's really incredible to see how quickly the deplatforming chickens came home to roost. We're now shooting ourselves in the feet at Internet speed.
