Well there are 49 subscribed people on patreon totaling $170/month. Lots of people probably already have accounts set up which makes it a very low threshold to join.
Meanwhile on librepay, arguably more philosophically suitable, there are 11 subscribers totaling $13/month.
Man, considering how many people I have seen saying how great it is to be able to pay, and asserting they are making donations, those are very low numbers.
