Google created the youtube "moat" by giving away the service for free for 15 years. In that time, an actually good, sustainable, paid video service could have emerged and everybody would be ok with it. Instead we got current Youtube, with its inescrutable algorithmic feed, content restrictions, and demonetization rules, and Google are asking us to pay for that with the argument that nothing else like it exists. Of course it doesn't, it couldn't exist since free Youtube was in the way.
