I guess YouTube's ruthless policies regarding profit sharing (even some other than the commercials thing you mentioned) are a blessing in disguise for decentralized platforms like Steemit blockchain and to be specific, for DTube. I'm sure a lot of traffic from YouTube, and serious talented people, are on their way to Steemit. I personally know a few who are already thinking of winding up their setup from YouTube and a couple other platforms and shifting it here. They're a big hit here locally in Pakistan. I will post a news once I get a confirmation from them.
