I see what you are saying, but Google is still not bleeding money and YouTube has become very well established already. In fact, for years YouTube contributes to Google’s primary revenue source: Advertising. Of course, this is why they are opposed to ad blockers, that much makes perfect sense.
But I don’t see any indication that it’s not making ends meet. And I’m not taking an executive’s word as proof, much less one from a whole different company. It’s expected that they will say whatever make their actions look good, whether or not it’s true.
