Do you REALLY think that Google is not able to block you altogether, if they really wanted to? The have permabanned entire companies and all the personal account of employees before for a misstep of one of these employees. It's just a matter of time.
That could be true. But if they decide to do that, they are gonna need to invest a lot, and if they success they are gonna lose a lot of viewers. Because for the mayority of the people, when you are use to ads-free, going back to ads its wonna be very difficult.
