The DS youtube page is like the wild west (end). Seems anything can go on there! I wonder who runs it.
Seems not too bad to me actually, they do a good job both for the MK channel and DS channel, and many others. What's the problem with some of the bootlegs? They just want to monetise it that's all. I think it's generally a good idea to have everything in one place, but of course, I'd want more official releases.
I wasn't complaining, it's just unusual. Paul Simon's youtube would never have bootlegs or fan made guitar lessons, but that's probably because he's not as good a songwriter as MK. 
Haha! I see what you did here!
But it's an interesting topic. These official channels sometimes seem extremely boring to me. What do you get there, "new releases"? Which are pretty much always just repacked old material, old performances, old everything. Stuff you can already find in your music collection or on streaming platforms anyway. So it's actually not a bad idea to feature some fan-made content, AS LONG AS it's good, of course.
I think all the legacy artists (let's call them this way) will eventually do something like this. You have to come up with ways to keep interest going. I wish labels would be wise enough to invest some time and money in things like proper bootleg uploading, possibly podcasts or interviews or something. Not merely a channel filled with boring official stuff for monetisation's sake.
If I go to Paul Simon's channel and see a proper, artist-approved lesson on how to play "Rene and Georgette Magritte with Their Dog After the War", I think no one on this planet would complain about it. So it's a matter of care and wisdom from artists and managers, something we don't see often, unfortunately.
I mean in the old times and even to this day they would bother to release all these (sometimes awful) tablature and chord books and whatnot, or even video tapes with artists themselves teaching, so why not go to some of the video lessons? The modern solution to old problems.
