That's quite a drawback. I don't mind supporting some creators and YouTubers through Patreon or YouTube membershops because $5/month isn't all that much. But if I had to make a decision to spend $60 to support them that much for the year, I doubt I would do that for most. Some charge $50-$100/month on Patreon for certain benefits too, I doubt many would be willing to pay $1000 up front for that for a year.

I'm surprised this is a payment processor limitation. I thought Stripe supported automatic recurring payments?
