Of course. I think I could give a separate speech about only that subject.
1. Nostr is a different group of people, and already an established censorship-resistant protocol.
2. A little bit of fighting is good, as long as the network isn't broken by it.
3. Nostr is fundamentally an Independent's protocol created by and for Independents. Not custodying the keys is the most important choice I made.
I think there are major advantages to this design and you're underestimating how seamless it is to move between servers. You can use multiple Ditto servers (and regular Nostr clients) at the same time. Megalomaniac admins will still prefer to just use Mastodon.
