So breaking up Google would have resulted in worse outcomes for consumers 10 years ago, but it would be even worse today? Then it wouldn't have made sense to break them up 10 years ago and it would make even less sense today.
I'm not claiming there aren't any good reasons to break up Google (I don't know), but this line of argumentation doesn't work as far as I can see.
Your argument only makes sense if you start from the premise that Google should be broken up, and then try to back into an argument supporting that premise.
I don't think it's a good sign that you decided to resort to baseless personal accusations in reaction to a simple request to support your baseless clams.
The question is very simple: does it still make sense to break the company today? Not a decade ago, but today. It you believe so, why?
