Every app has power to censor people, no matter how 'real nostr' it is. Someone's there to blacklist a pubkey and push the 'commit' button and the app gets distributed to it's users one way or another and someone gets censored. The motives for blacklisting don't matter, but I've seen enough in recent years to know that's inevitable.

And I'm not even mentioning the lighter things like changes in design or features. App starts prioritizing Repost instead of Zap button and my audience's behavior changes without my control. Outbox doesn't fix that either.

I'm not saying outbox is failing/wrong, it does the job at the relay level and makes bans in 'real nostr apps' much less likely. But it doesn't solve everything.
