Wasn’t Parler take down reactively, as a response to the users’ behavior and content on the site?

That seems different (and significantly easier to justify) than blanket bans based on some algorithmic analysis of an app’s name.

Sort the difference between banning one person from your store for being loud and disruptive and banning all people that meet a certain criteria.

I’m not saying google is or isn’t within their rights in either case, but they do seem different to me.
