Rooster Teeth (of "Red vs Blue" and "RWBY" fame) did the "indie filmmaker on youtube" thing pretty successfully. Eventually they moved to their own site, then fell apart after a lot of drama and internal differences.
Also vaguely guestures at all of youtube. Most youtube creators are independent, and a lot of them have higher production value than indie movies. You just don't recognize them because of how the algorithm and monetization favor regular installments of ~10 minute episodes, causing most content to take that form. A documentary simply works better on youtube as a Tom Scott video than as a 45 minute piece (though there are plenty of those too)
