My primary worry here is that this would hurt the open web - whether or not splitting out Chrome into a separate business would be good for consumers in and of itself. It's true that Google adds a lot of things to Chrome or their own benefit or even the potential detriment of others like Mozilla. That being said, they also do a tremendous amount of work to push the state of the web forward and, most importantly, they…
Google has to be dismantled in parts one way or another - too much control over search and Youtube to the point where they are able to enforce Chrome standards that prevent adblocks from working.
Youtube needs to profitable somehow, and advertisers are the best way to do this. If Youtube couldn't generate the revenue through advertising, what else can they do?
It's insanely expensive to do video streaming, hence why Google invests a lot in the new compression formats today, WEBP, Brotli, AV1.
Do you just expect them to just do all of this for free?
