One could also say that Google has proportionally more to loose from the advent of privacy consciousness in people and companies - namely the latest moves by Apple.

But at the end of the day, with most people still using Chrome and giving away their browsing history to Google without a second thought, I don't think Google is too worried at this point.

Everyone other than Google - no data

Google - all the data

That's what this is

Do you have any actual technical counterpoints?

I think the problem is the hens are watching the fox design the coop. They've been invited to participate, but the fox has unlimited resources at its disposal for research and planning while the hens are of meager means.

So yes, it may be unkind to prejudge the fox, but based on years of prior malice towards all poultry in the yard, and without fully understanding its plans, we have to assume it won't turn out well for us chickens.

Cluck.

No because I wasn't commenting on the technical aspect. A proposal can be both technically sound and wildly monopolistic at the same time.

Not everything is a pure engineering problem.

Why are social and economic arguments against it invalid?

Personally I didn't even bothered to read the proposal. No need for technical counterpoints, it's made by Google.
