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.
