Because this will mean major shift to open-source and community solution, where creators will be paid directly by their viewers.
I have NO problem, what so ever, to pay content creators directly.
But I have HUGE problem to pay big corpos. It's ridiculous that we pay for Netflix same price as US people and for you it's cheaper than coffee and for us, if you compare median-salary, it's 5-10x MORE expensive. (cancelled every streaming platform year before as all of my friends, cloud seedbox here we go) And I don't even wanna mention Netflix's agenda they want to push (eg.: Witcher)
That's why piracy is so frequent here in small country in EU :) Also it's legal or in grey-area, because nobody enforce it or copyright companies are unable to enforce it if you don't make money from sharing. (yes, you don't even need to use VPN with torrents)
You are not standing up for them by pirating their stuff from YouTube.
If you have a problem with it, it is on you to stop using YouTube to view their content. You did not gain a moral right to pirate their stuff just because you don't like the deal.
