To quote another comment I made:

It would be, if Google didn't have a chokehold on most of the internet. Sure, Nebula exists, I can watch three creators there, woohoo. Let me go on Dailymotion too for those sweet 2005 videos.

Google did everything in their power to force themselves into every aspect of our lives and leaving no alternatives, or destroying them, or buying them. Now they get to deal with the consequences

The content creators could post anywhere, there is no reason they can't cross-post their videos to other platforms. Most publishers who are on Patreon post all their videos ad-free on there so you don't even need to go to YouTube.

The reason most publishers post on YouTube is because they depend on the revenue from the YouTube network.

If you don't want to watch ads, fine, but you are expressly violating the wishes of the people who are creating the content and then rationalizing it to yourself. The fact that you still rationalize not buying the ad-free premium offering is the kicker.
