"Produces money"? "Payment information"? I think we misunderstood each other. If you want a way to receive donations, you can publish Bitcoin address. If you want an elaborate way to enforce payment and produce money out of voluntary but unconscious decision - yes, Patreon is the way.
I know that the best thing you can do from SaaS perspective is to get customer's credit card and permission to bill small non-defined amount indefinitely, but I find it morally wrong.
Still, I don't think that WinRAR would have many paying fans on Patreon.
"If you want a way to receive donations, you can publish Bitcoin address."
Yes. If you want payments, you can publish a Bitcoin address, or anything else you'd like (my point here is not about Bitcoin specifically). To a first approximation, you won't actually get any payments, though.
That's the difference.
We don't live in a world where people haven't ever tried this brand new donation idea. We live in a world where a lot of people have. Their reports are almost uniform... they literally write blog posts when they receive enough money to pay for a meal in a month or a year, because that's how rarely it happens. It's not a functional mechanism for making money. It doesn't even rise to the level of paying for a hobby; it tends to run at donation rates roughly comparable to what the author could get walking down a busy street every day and keeping their eye out for loose change, and well below the rate of "collecting bottles out of the trash" in any state with a bottle deposit.
