>You, a viewer, are nearly irrelevant to YouTube. You exist purely as a revenue source

How are these two statements not contradictions?

Rephrase it as "Youtube doesn't care about you, just about putting ads in front of your face" and it's not a contradiction. As long as you don't get irritated enough to go away and stop using Youtube entirely, they don't care about improving your viewing experience.

Another way to phrase it is the classic line "If you're not paying for it, you aren't the customer, you're the product."
