Antitrust enforcement is so scattershot, varying over time and depending on current us administration. It's like an entire higher level of abstraction over the problem. And in practice we have extremely little antitrust enforcement in the us over the last 20 years. We'd have to theoretically fix antitrust enforcement, then eventually "market forces" would force google say, to improve customer service.
Google is not going to change, they are one of the trillion dollar babies and they can just ignore us. Just like apple. What anti-trust enforcement could cause them to change? I'm skeptical the new EU rules about how "open install of apps to breakup app-store monopolies" will work to effect change.
Google ads are a natural monopoly, like power lines. What are you going to do, go to 1/3 of its ad customers and tell them they're switching to Southwestern Google while another 1/3 have to switch to Pacific Google?
And then one of them becomes dominate after 5 years, and the other(s) fold. It's an inevitable problem. The only way to "break them apart" that would make any sense at all would be to break off distinct divisions, like Search, YouTube, Gmail, Google Cloud, etc. Into separate companies. Then forbidding them to acquire each other, and generally be extremely pessimistic/restrictive if any of them attempt to acquire any company at all.
