I think a lot of people that use the big social media platforms are mistaken with how much ownership they have of their posts. Sure they can monetize videos on YT, edit it, but they are still at the mercy of the company. I've seen people get demonetized or even get banned for no clear reason. It is also difficult to get it overturned. So I agree that Web 3.0 could be helpful. While it can't stop people from taking the data, its transparency will be able to make it easy to tell which is the original.
