It's interesting and I'm glad it works for independent artists, but the cyncic in me knows that if it were to work on a large scale, some ad-tech company would figure out how to game it.

From the Patreon wikipedia page:

Artists set up a page on the Patreon website, where patrons can pledge to donate a given amount of money to an artist every time they create a piece of art, optionally setting a monthly maximum. Alternatively a fixed monthly amount can be pledged

So it either turns into a monthly subscription fee, or becomes another game for the ad-tech industry to solve.
