Because they don't understand how Nostr works or what it is. They think it's just a new Twitter with some centralized authority picking favorites, so they are appealing to the Nostr CEO.
Its not "New Twitter", but if one dev I know got his way... On SSB, everyone is a relay. People complain about NAT, but Tor fixes that. SSB was an even harder protocol to attempt to centralise than Nostr. But he tried and tried. Wish he'd keep to his little Fediverse dictatorship, folks like this sort of thing there...
Yeah haven't a clue how it works really, but hey, you know. . . Shit sounds creepy and wierd, watchagonnado? Ask questions and stuff, try and figure it out a little. Not everyone is going to read all the nostr whitepapers and know all the nuts and bolts, but most of us care about it nonetheless. Many came here to escape censorship, and so we're emotionally sensitive to things that sound censorshippy frankly.
