It is apparent that the people at Google don’t understand that everyone uses YouTube ONLY because it is free to use. When there are a dozen other sites to host your videos free of charge, and YouTube is monetized, YouTube will collapse in very short order.
They are supposed to know how to make money, so why are they talking about this? This reminds me of the United States Postal Service constantly increasing postage rates because of dwindling revenue. Note how well it’s worked out for the USPS.
