I'm guessing the misconception is that all those creators would run public free open-to-all relays and face huge scaling/moderation/legal costs. That's obviously a bad idea and won't happen.
But does an average wordpress site have "comments"? Yes. Does author have to moderate those comments? Yes. All blogs are already tiny "relays" that have some costs that creators pay for. Again, nothing new.
If nostr is adopted, creators will have relays to host their own content, and to host legit reactions to that content - other events just won't be accepted. It will require some moderation and some costs, but that's a completely different thing vs managing a big public relay.
And outbox model will deliver you the twitter-like experience even though the content is scattered across a hundred relays hosted by creators you're interacting with.
Will there be big relays? Yes, twitter will run one, meta another. Will creators rely on them? No, not exclusively. Creators will run their own, that's the whole point.
And if DNS/hosting provider kills their relay, they'll just rebroadcast their stuff _everywhere_, until they set up a new relay in a different place.
Thanks for coming to my TED talk, as they say.
That's cleared a couple of things up. So in normies words, instead of paying for a web host for a wordpress site, I pay for a relay. And if it were targeted, as in shut down, I can offload the content across multiple relays til I'm ready to start again off my own back.
If so, why not set up from the get go with different federations of hundreds of relays and via the handy payment system built into Nostr, I am set up to pay like 1 sat/day to each relay runner. That way, in the event of relay takedowns the average Joe doesn't have to broadcast or run around setting up a new relay, and the pros would set themselves back up quicker and easier.
Automatic pay-per-use is nice idea and I want it explored, it just hasn't been built yet, so it's hard to predict how that will factor in. My point is that it's clear who has the incentive to pay for relays - creators, by running a relay or by outsourcing it.
There is an option on hablanews, fountain to split income with selected accounts. That's the basics for sharing your $5 a month paid relay fee across a. bunch of relay runners.
