Patreon – no. You pay a subscription to YouTube and you don't get served ads. Some of the money from these subscriptions is then divided between the creators, similar to how Spotify works.

YouTuber makes more money on average when a YouTube Premium user watches their video than what they would get from the ad-view if the person wasn't on Premium.

All in all it's reasonable IMHO. I might purchase it some time. The only issue is that this of course doesn't remove sponsorships baked into the videos, which annoy me just the same as the YT ads. So, I would still need Sponsorblock.
