Indeed. I always encourage people to setup their own relay and stream/sync with nostr:npub16fcy8ynknssdv7s487nh4p2h4vr3aun64lpfea45d7h4sts9jheqevshgh since I do not have a vested interest in selling RaaS or subscriptions. 😉

There's also the second-best option of exporting your notes to a local file so you can reload if they disappear. (With e.g. nostril-query --authors | nostcat wss://relay.example.com)

I do both, because "two is one, one is none."
