YouTube is currently being mismanaged into the ground, they won't vanish, but they are pushing every individual content creator that isn't part of a bigger company (like Disney, for example) away from YouTube. So I'm hoping that this will make bigger YouTubers at least consider alternatives such as DTube. And yes, this is a long shot and probably won't work, but if it does work (on the off-chance) the steem blockchain will finally get some recognition
