Unless you have some first hand information that I have, you are more than 10x off.

> I refuse to buy Youtube ad free until they drop the price to something $3 or below...

There in lies the problem. Your eye balls (assuming well employed with $$$ disposable income) is another 10x worth to advertisers.

If I were to make a guess, Youtube for sure will lose money at $14/month on your specific browser.

You are literally subsidizing internet for, let us say for arguments sake, some zip code in rural america or <sub any rural part of the world> 's Youtube streaming needs.

At least in my case, I had Youtube Red and would watch a few hours of content per day. Then I canceled and found the ads so unreasonable that I just stopped using youtube altogether. Now they make no money from me.
