I saw a YouTube video by a guy who specializes in building D&D characters. He spends twenty minutes going into detail on each one, and then makes the pitch for subscribing to his Patreon account with something like "members get all the details in a convenient list so that you don't have to keep going back to this video." So he's using the same bit of friction that this article is trying to solve, to fill his rice bow…
Maybe if your business model includes putting things in an inconvenient format that could best be replaced by a bulleted list, you should rethink your business model.
I wish we'd go the other way, where free text content is complemented by paid-for audio or video commentary. But it has to be a very dull video for a bullet list to be a good replacement (and a bad bullet list to be able to capture what a good video production can convey).
