The difference is whether or not it is an official release from Supercell. The video links are posted by Supercell Staff which leads to the assumption that they are from Supercell and not the private views of an individual. Honestly, until today, I did not realize that Galadon and Chief Pat are not Supercell employees, or at least that is what I have managed to learn from these forums.
Whether they have their facts correct or not is not the issue and while I am not paying to view the videos, by visiting their YouTube channel and viewing the videos, those individuals do indeed make revenue from my visit to their page from the ads on their YouTube channels, etc.
