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.
