Great. Good for them. What about the rest of the world, some (many) of whom can't afford a(nother) monthly subscription fee?
Are they now to be excluded from participating in popular culture, if they do not wish to be subjected to obnoxious advertising?
Youtube basically reached a de-facto status of a public library, considering it contains archival TV shows, sports matches, original music, documentaries, lessons, instructions, clips of contemporary life, and so on. While median quality is much lower, it easily rivals Wikipedia in breadth and depth.
It my opinion, it should be publicly funded, without discriminating access based on willingness (ability!) to pay or to be subjected to ads.
