Nostr isn't just free speech.
It's your freedom to @ anyone and theirs to ignore you.
I can ping Kieran or the Primal devs if I really want to but it's a lot like IRL if you were at something like a meetup. They might notice you, but could also ignore you if you were too annoying.
I kinda like that. :) It's like, they're not "far away" like how it feels like trying to interact with peeps on Twitter or Instagram. o.o
Could also just be my perception...
