The advantage of YT is the massive audience there, and it is also a search engine. The ability to change things like thumbnails, links etc is an advantage. With DTube, things are "baked" and you can't change anything after 7 days.
Some videos are evergreen so can earn money for creators for a long time vs 7 days. But it is very sad that everything got deleted. No time to even inform subscribers.
I learned as a child that when the masses are running towards a cliff face, it might be a struggle to go against their direction, but it's better than destruction!
