Everything I had read says that the reason it was taken down was because of what users did on the platform. They did not want those users accessing the site, and so they went after the platform.

We could all be cheering for the fact that the powerful went after those users, and then be angry when they go after users we want to protect, but I don't. I rather want to promote users ability to choose themselves if they want a filter that removes Parler members from their own devices.

On HN there is a setting which allow users to see dead comments. Its a user setting. There could be any number of dead comments and yet users can see them if they choose to do so. Such a simple choice makes a rather large difference in the power relation between HN moderators and HN user. Without it this whole discussion could not even exist as the parent comment is dead.

Parler had contractual obligations with AWS that they violated, were given opportunities to correct the violations, and were unable to do so. AWS hosts more objectionable content than Parler, but those parties are able to keep themselves within the bounds of their contract. It's that simple. Parler wasn't censored, they breached their contract and so their contract was terminated.
