Yes, but not until Apple allows the next update. You’ll be able to filter global by only paid relays.

I am not paying any relay, only add those paid relays to your profile and you be able to read for FREE from this paid relays. Paid is only for push events (write)
Yes, do this. Most paid relays are read-only, so you can still add them and they’ll popular your global.
Ultimately, though, they’re cheap. I’ve earned far more in tips than I’ve spent on paid relays.
Is confusing when you said to a newcomer : you must "add the paid relays" he could think he needs to pay for everything and this is not the nostr spirit.
Where can I find a paid relay?
