This just means that Youtube isn't worth the ad watching time for them that Youtube feels entitled to. I personally, for example, will continue watching Youtube with an ad blocker but I'm also perfectly fine if Youtube closes entirely or becomes subscription-only.
This is a fact that internet publishers simply don't want to accept: the value of what you're offering is so low, that the most I'm willing to pay you for it is zero dollars.
This affects publishers both large and small, from Youtube to mommy bloggers. Like all those recipe blogs filled with bloat so they can stuff more ads. And the passive aggressive popup complaints about asking me to disable my adblocker: absolutely not. Sorry dude, but the value of what you're offering is worth "free" to me, and you can prove this to yourself by switching to a subscription payment model for whatever you're publishing. You'll make almost nothing compared to what you make from ad revenue because what you're offering just isn't as valuable as you think it is.
