The problem as I see it are the "irrelevant ads" which do not pertain to the subject matter of the video. An example is below.
I spend a great deal of time searching for longboard surfing videos since I started longboard surfing when I was 15 and I am now 75 years old. That is a long stretch of 60 years. Below is a short surfing longboard video show casing Quintana Beach on the upper Texas coast where I do most of my surfing.

Before I could view the video, there was an ad for the Ozempic weight reducing drug. This drug has NOTHING to do with surfing. Would I be interested in viewing this irrelevant ad? The answer is "no" because I weigh, at the time of this posting, a MASSIVE.........wait for it.........134 pounds (60 kilograms).
Show me an ad for anything with respects to surfing such as surfboards, fins, wetsuits, board leashes, board socks, board bags, etc and I will watch the ad. It is simple as that.
Whoever at YouTube who is in charge of advertising or marketing, this person (or group of people) might be smart, but when it comes to common sense, he/she (or the group) has ZERO common sense.
One time, I was looking for a surfing video for a few longboads made in the new Thunderbolt Technologies (Red & Black construction). I did find the video, but there was a short ad before the video. The ad was for Thunderbolt Technology in Red construction.
I said to myself, someone at YouTube has common sense.
The ad was highly successful and many surfers wanted to know more about this new technology. The japanese company who made the short ad decided to make a video show casing this new technology. And the video, which is a little bit longer than the surfing video above is below.

I am not a power user in computers; but I do comprehend the logistics, engineering, materials, equipment, physics, math and innovation in making a board in the above video.
Give me a relevant ad pertaining to the video I am going to watch and I do not have a problem with ads. But if YouTube is going to push irrelevant ads, then YouTube is going to play "whack-a-mole" by going after ad blockers.
My CJ Nelson 9'3" Parallax single fin longboard is made in Thunderbolt (Red) construction and the video above is what drew me to their website for more information.

The surfer who designed my Parallax is CJ Nelson along with the expert shaper Ryan Engle. Cost for my Parallax alone, $1300 US dollars so the original short ad made some money for YouTube.
