You see YouTube is a American company and in America every thing is extreme you ether have a lot of ads or no ads you can have a extremely massive car or a cat that's soo small it doesn't exist
The whole reason is to either make it so annoying that you switch to their paid service or get as many ad dollars into the shortest amount of time possible either way. This is just greed to squeeze as much out of the consumer before they break us.
Straight up what made me switch to YouTube premium was a bit of a 2 pronged thing really
They started including Google Play Music with it, and then I got an unskippable 1 hour ad in front of a video that after I reloaded the page I got the same ad again.
Edit: I don't have an issue paying for a service if the price is right. I got what I wanted for I price I'm willing to pay.
They bundle YT Music in your subscription because they wanted a share in music streaming, invested in an infrastructure on their platform and then realized that their service doesn't offer enough to make people want to use it over their competitors' music streaming services. Instead of taking that loss or making their service worth using, they bundle the shit nobody wants with what everyone needs and use that to justify a price hike.
If there was a basic subscription that just removes ads on the videos I click on without any other useless crap attached to it, I would pay for that. But no, it's predatory, anti-consumer bullshit, so I just block their ads.
