Pretty sure you’re focusing on the wrong number out of the two

Despite what you observed in your circle of friends, Facebook still have millions of users in the US and billions world-wide.

I’ve used the alternatives and the experience isn’t really nearly as polished and consistent as using the YouTube app, especially if you just want to sign in and use your YouTube account. I’m not saying premium is cheap but it’s really not out of the ordinary to pay for the service as some people think it is. There are also YouTube kids and music that provides some value.

If there are DNS blocklists that work for YouTube, please provide a link or guide.

If you’ve used YouTube on anything besides a computer, then you would know that the experience is suboptimal.
