But how do you break up Google? Their ad business is the lynchpin to their monopolies and breaking off chunks without being able to self fund is just asking for harm to the market.
Breaking off Chrome while banning paid default search status puts the browser company with the same problem as Firefox.
No one can run a search company without ads.
Cutting along business lines is just going to create smaller monopolies or dead product lines.
Because the ad monopoly is subsidizing the other businesses.
Breaking up Google to smaller companies but leaving the ad market as is the same just creates more Mozillas, companies technically independent but still relying on the same revenue stream.
