If Google is subsidizing everyone else’s consumption of video, pricing it below market, that’s a good thing. Someone giving you free money or a discount you b didn’t even need to ask for is a good thing. Dumping out selling below cost harms no one but the seller.

It hurts anyone where the product doesn't meet their needs, and their needs would be met if there were several healthy competitors.

it gives too much political power to Google. If google decide to ban you from youtube, you become non existent.
