I disagree further from your position in that if the default allows them to censor posts it is unacceptable. They are claiming to be a Nostr client, but you are really not on Nostr at all. You are on a separate completely different service that happens to pull content from Nostr, but you have no assurance that will remain the case in the future. The default for every client should be to read from relays, and aggressively add new relays. If people don’t want that behavior any alternative should be opt-in and not opt-out, to not defraud and confuse the technically uninclined into believing that they are using Nostr when they are in fact using a completely different thing.
