I've been trying to use some of the alternatives mentioned in the OP. I'd be happy with some of them from the aspect of political and other news, as well as some of the entertainment videos. However, my main use of Youtube has been for reference videos, mostly "how-to". They have been invaluable to me, even when I have had written instructions for some things. Watching a step by step though, has often made the difference, especially when people point out stuff the written instructions don't tell you. Also product reviews.
I simply can't find those kinds of videos on rumble.
