I disagree with almost everything you just said, as someone who has bounced back and forth for almost 4 years now.
To take the video lessons, chess.com are clearly leagues ahead of lichess. They can pay the contributors to produce quality productions. You can't really open source the time of experts .
Frankly, who gives a shit about someone's opinion who can't even handle a comment like 'I disagree with you' without hurling personal insults.
I mean in theory, nothing prevent a professional chess player to make a nice video lesson and share it for free. And there is no reason to assume this video would not be as good as videos made for money (just like it's the case for software)
