DTube is different on the back end technology wise, but the practical reasons are at the very least:

  1. Content creators are paid using the Steemit, steem currency model instead of the ad revenue model. That means their content cannot be demonitized by the platform.
  2. Content cannot be censored by the platform. Copyright, libel/slander, etc. claims can be filed of course, but that is(presumably) between the company filing the claim and the company hosting the video.
  3. DTube offers diversification away from Youtube, which is virtually a monopoly due to other alternatives sucking either through poor UI, poor community involvement, poor monitization scheme, etc. So if Youtube were to fail, it wouldn't be game over.
  4. There is no banning/termination mechanism that I know of on DTube, so creators won't wake up one morning to find their accounts have been locked/terminated like they could on Youtube.

well explained, thank you!

the main difference is that dtube works on the Steem blockchain

In addition to what abuyeti says, Youtube is owned by Google for some time now and they operated it at a loss year after year in order to keep the huge marketshare and mindshare Youtube has over online viewers of content. There is no silver bullet for marketing online in a way that generates profits that any reasonable business can operate off of, and many other app-type of services operate at losses because they are funded by investors who hope that the gamble that sinking more money into such businesses will pay off when they can either flip it to another set of investors or IPO it. I know many content upload or streaming sites have failed in the past and the few successful ones seem to get bought out. Decentralization takes some leverage away from the big players like Google (Youtube) and Amazon (Twitch) and back in the hands of the users and producers.

I found this link explaining what dtube was (not sure if it's all still applicable as this was the release post)

It's open-source and appears to be made by someone who actually cares about users, which is arguably a much different approach than most of the big dogs.
