You still lose Google more money than someone who views the ads and never buys anything on the ads.
You didn’t lower the value of Google’s ad network by being less likely to buy things off of advertisements, but you still cost Google 100% of the bandwidth, storage, compute, and labor costs required for you to serve the video.
Hypothetical Example:
Let’s say serving one video costs 5 cents in fixed costs. An advertiser pays 10 cents for an advertisement to be shown to you. The average YouTube premium subscriber pays roughly 10 cents per video and didn’t get shown an ad.
Let’s say you never buy anything but watch the ad. Google got their 10 cents but because you’re the type of customer who will never buy anything, Google’s ad is now worth less. Because you’re such a bad customer Google lowers their ad price down to 9 cents per view, because we can assume that maybe 10% of people who watch ads will just ignore 100% of them.
That means you made Google 9 cents, minus 5 cents for fixed costs, that’s 4 cents in profit.
Now let’s say you pay for premium. The math is obvious, 5 cents of profit.
Now you watched the video with ads blocked. Google paid 5 cents to serve you the video, but nobody paid for it. Net loss is 5 cents.
I know the numbers are far off and made up but you get the idea. People who aren’t susceptible to ads are already baked into the market price of ads. A response rate of something like 5-10% for marketing emails is considered excellent.
If you block ads and don’t pay for premium you’re not even a customer. I realize that that’s not your problem, but again, it’s Google’s prerogative to refuse you service.
And you can call advertisements psychological warfare and perhaps they are in some way, but I don’t see how society would function without them. Basically everyone advertises, including on the individual level. Inviting your friends to a party is an advertisement. Does your employer advertise? And you work for someone who engages in psychological warfare? How could you!! But seriously, how do you develop anything new with the involvement of more than one person without the ability to evangelize it? How do you exchange goods without the ability to make your presence known?
As long as advertisement is moderated in some way it’s just a normal reality of living in society. It’s basically just communication.
