IIRC it's a 3+ hour video. It takes a lot of dedication to watch it through, or a lot of love for Ryan. If you're familiar with Ryan's work, however, you know he carefully sources everything, and can assume he's going to decry corruption, war crimes, and oppression, which is in line with most rational assessments of politics. Supporting creators may not require actually watching 3+ hour videos.

Not saying you're wrong, but I can understand why folks that don't always watch the videos support him anyway. They're not voting based on the specific content alone, but the work, the person doing the work, counteracting censorship on other platforms, or doing so based on other reasons.

Edit: I don't think curation rewards alone account for his support, but I don't consider curation rewards at all when voting, so I don't really know what matters. I assume that the more popular content is the more rewarding curation rewards will be, but dunno really.
