Yeah - I had a quick look through my feed. From the image URLs most seem to be using the free version. I can imagine how hard it is to even break even right now.
Ideally everyone would share the burden, but new Nostr users aren't going to see the value at first. I do think a lower price point would help with increasing the number of subs.
I wonder if an automatic free trial also might be worth exploring? After the trial, the npub would have to use one of the less ideal image hosting services.
