I can only speak for myself. I have no idea what would make a sustainable business model.

A few years ago I had a sustaining membership to a very popular public radio program. I dunno if it was a dark pattern, an oversight when overhauling their webpage, or what, but when I had to update my credit card number because it changed and I could not figure out how. None of the email contacts got any response. I eventually cancelled the old number and I've been hesitant of reoccurring transactions since.

Conversely, I would use PayPal to manage other reoccurring donations. I've adjusted the amount, updated my credit card, and canceled without issue. I was never a fan of PayPal and closed my account a few years ago, and this activity seems to have migrated to Patreon.

The web is weird and surprisingly still lagging cash and brick & mortar in many areas. People are soured to the experience of buying music and merchandise from a variety of sources and have been funneled to specific retailers like iTunes and Amazon.
