I hate apple but in this case at least apple users are paying the relay for everyone else 💁🏻‍♂️

I always want to see who I'm paying and know the exact price and what I am paying for. I think bundled financing, like with Damus, is just a relay business model that makes sense for some client developers, although I'd want premium relay service, if my subscriptions funded it. No throttling, longer retention policies, etc. I see other business models focused on relay management, for particular user bases or use cases.

Most free relays have 3 people writing to them or they seem to not last very long. Every person can just host their own "free to them" relay, after all. Nobody is going to be running a "free" relay for thousands, or even millions of people, just out of altruistic intentions. That's a full-time job with serious infrastructure, legal, and energy costs. Basically sys admin.
