I'm glad the majority of companies aren't active nostr. I don't want even more corporate goo in my timeline and since only a very few companies offer decent social media support in case of issues with their product(s), I'd rather they stick with Bluesky/Mastodon/Threads so I can keep my peace. Got nothing against small shops/makers/artisans that are actively engaging with people and have a real personality. I'm following lots of them myself and purchase their products if shipping costs allow it.
I really hope nostr will have sufficient time to develop its own culture before people inevitably notice that freedom of speech is actually important. I guess people will have to burn a couple more accounts on X/B/M/T/FB before seeing the light.
