Amethyst isn't a company as far as I know. Many nostr implementations are just open source projects.
For those of you who are still on Twitter, I had a long debate thread today with Parker Lewis about Nostr. I'm a big fan of Parker, so I figured I'd share it here for shared learning.
Here's the latest post. I'm not sure it'll be the last or not but it's the latest one as of this writing. You can scroll up to see the exchange from the start.

Linking to my own post in isolation is bad form and the thumbnail is awkward depending on what client you're using, so I'll also provide a pic of the start of the debate too, with two posts of his and one of mine.
I'd be open to any thoughts about this debate.
Discussion
They are mainly talking about relays, not clients.
