If you mean Nostr - whichever client you use - then yes. And, in my honest opinion of being almost two weeks here now - it is. By a lot.

Sure, it has toxic things in the timeline when you look at global - which also depends on your configured relays - but you know that your data isn't used to feed an algorythmn or profiler to serve your ads and you aren't served specific tweets on purpose.

Thats what I love about #Nostr
