YouTube is not doing it, I use YT premium and I never get a single ad. Ever.
And I know that ad supported cheaper versions of a lot of streaming services are becoming more common, but, to my knowledge, all of them have an ad free option. It may be more expensive than their cheapest tier, but they do have an ad free option.
If you want to see the internet less dependent on ads, the only way to do that is to be willing to pay for it yourself. Because streaming video content online is actually extremely expensive to do. And someone has to pay for it. If you as the consumer aren’t paying for it then someone has to pay for it on your behalf. They’re only going to do that if they can get something out of the deal.
