This all comes down to consent: someone who pays for a billboard knows that not everyone will look at it, people who create open source software or open standards know that other people will use their work to make money, etc.

The problem is that YouTube is not providing free video but rather ad-supported video. If you don’t like that, it’s like seeing someone else’s GPL code: your choice is take it on the terms offered, negotiate other terms, or don’t use it.

Someone who pays for a YouTube ad knows some people will block it. And advertisers do not value consent.

YouTube advertisers aren't affected by this - it's the content producers who aren't getting paid, and potentially even YouTube no longer making enough to pay for the resources you use. YouTube has an enormous library now but if people who make content start thinking of it as smaller and smaller payments they're going to making new content.
