Firstly, the entire point of YouTube for me is the long tail. I don't watch any of those channels you listed, and the only two I've heard of are Linus and Adam Neely.

But the more important point is that even if all the many dozens of mostly small channels I subscribe to were on some other paid video service, I wouldn't want to track down and check in on all those services. Even just 3 would be a vastly worse experience than YouTube, especially since there would almost certainly be huge variation in the features and quality of their various web, mobile, and TV apps.
