The biggest problems with DTube are the Steem blockchain's problems. It takes forever to get a Steemit account approved, and then your vote means shit unless you buy money into a crypto whose value goes up and down. Don't get me wrong, I believe in Steem, but you have to convince people to invest in something before they are able to even support you, when Youtube asks you for nothing. The only alternative is to pander to whales, but then what's the difference between changing yourself to appease advertirsers and changing yourself to appease the whales? Either way you're their monkey dancing for money.
