> - I can't upload random video to the netflix, and I have a certain expectation regarding content there
That's a bug, not a feature. You're basically restricted to the tastes of Netflix's buyers.
> - 99% of videos on youtube are not something I would pay for or expected to be paid for uploading
Then you're watching the wrong videos. Most of the videos that I and my friends watch are high quality, entertaining, and informative. Their creators usually have Patreons making five figures monthly.
> - I can pay for youtube subscription and would still get a lot of advertisement, because I dared to turn SponsorBlock off. Creators have a very good reason to use this type of ads, and youtube have all responsibility of not providing solutions for this.
You can easily skip these, not sure what the issue is here.
> - I can pay for HBO max and watch Sopranos. On youtube I can pay and content of interest could be deleted next second
Guessing you started streaming only recently, since Netflix/Hulu/HBO all change their inventory frequently due to licensing. It wasn't long ago that you could watch Sopranos on Amazon.
> - I have no idea if my favourite creator was demonetised for DMCA spam by youtube, but I certainly know they are not treated as equal partners in this business in many ways.
This isn't a problem with YouTube, it's a problem with the US legal system.
> - Ultimately I pay for content, and subscription guarantees some kind of investment from the platform in acquiring or producing it. Not true for youtube.
This is your best one, YouTube has created tons of wealth for creators and has cut out tons of the usual Hollywood intermediaries. Additionally, there has never been a greater investment made on storing and distributing video like the one Google made on YouTube.
