We're talking about business models here, we're talking about a whole industry, and you should realize that your opinion is worse than useless, it's actively harming your ability to understand and predict
If PeerTube wants to be a 0.00001% write off for radical CopyLeftists and "Hackers" to put up some low effort, low value, "good" content then so be it but to even bring up Youtube in a conversation of yet-another-tiny-site is silly, because that concept is not competing with Youtube and could never compete with Youtube.
As for PeerTube I don't care. Sadly video is currently expensive to host and only Google has the pockets to operate a site like Youtube. I won't pay for it and the day my adblocker stops working is the day I stop watching it.
And yes there are some Youtubers whose I have subscribed to and their content is often great. However it is not consistently great enough to pay for it just like cable TV. And that is just the top 1% of the top 1%. Rest is at best mediocre and often just grabage.
