I have yet to see an educational content provider that isn't primarily funded from Patreon, direct sponsorships ("This video is sponsored by..." lynda.com, Audible, Skillshare, etc etc) or produced by an entity that has relies on external streams of revenue (e.g. BBC, PBS). Heck, even the "trash pop" part of YouTube (e.g. drama channels) don't seem to primarily rely on ad revenue anymore. And most of the gaming channels seem to actually prefer Twitch (but either want to editorialise their content rather than upload raw streams or only still use YT because they want a more diversified revenue stream). YouTube's initial appeal was that it was a "marketplace of ideas" and everybody could upload videos of pretty much anything and build an audience and (eventually) earn a few bucks from advertising. Recently that marketplace has increasingly shifted to promote what's already popular and YouTube has actively brought in established content producers from TV while also algorithmically demonetizing "lesser" channels (note: this doesn't mean less-viewed channels or channels with fewer subscribers) with little to no means of appeal. The gold rush when it was actually financially viable to make a living off the ad revenue and fund your video production are long gone for the vast majority of creators.
