I don't think that's comparable at all. Patreon is an entrenched 1:N (one website for many creators) method for giving money to your favorite youtube creators; youtube's new system is late to the game. Youtube is late to the game here in the same way that Amazon's Appstore was late to the game on Android (which I think maps better to this scenario than generic sideloading, since both Play Store and Amazon Appstore are both 1:N app distribution methods, just as Patreon and youtube are now.)
