ok, not just that... 

Some tele-doctors and writers tell that Meta (insta + FB) are still much more cost effetive than twitter/X:
that is, the same post, posted at the same time, generates more engagement, views, and SALES in Meta than X. Like 5x or 10x more.

And even X is still orders of magnitude more cost-effective than nostr. 

For these guys, posting is their bread-winner. A brazilian who sells events in X tried nostr, but it was not worthy his time. 

Sometimes we forget we are a little bubble, normies/NPCs are the vast majority. 
Not just that, full censorship platforms are still larger than X, even if for us they look like dinosaurs (of the carnivore variety).
