Let it die. Nobody pays for relay unless they're a business. And then, that business needs a reason to run besides charity imho

Some relays a more expensive. Some relays are cheaper. Some relays are $500 a month. Some are $5 a month.

I run more than 50 relays plus a bunch of other things for $5/mo. That gives us $0.10 per relay.

Well, Nostr.land is a much larger operation for example, with aggregation and such taking a lot more resources. Also one of the more popular relays. Doing a relative comparison, $50/mo is grossly inefficient for that size.
