You could give Odysee a try. I was pleasently surprised at how well it works, and how nice the UI/UX is. Especially considering it is a decentralized platform.
It’s missing a lot of the content that youtube has. Especially if you trying to look up a specific video or niche topic. But there’s still a lot of great content available if you are happy to browse.
I think lots of boomers and gen-x do care. (At least the ones I know). They just aren’t tech literate enough to do anything about it.
I think we need more privacy oriented devices and software with simple ux, and advertising that isn’t targetted at the tech community.
Run some TV ads for a privacy enabled smartphone, and play up how it works just the same as your current phone but doesn’t spy on you. Shit like that.
