What will breaking up Google accomplish? I think the individual orgs inside Google already act as separate businesses. So they are already split internally.
In my opinion, Microsoft became a much better company after their brush with antitrust. I don’t know how much had to do with the case and how much is just because of the quality leadership they have now, but I hope Google becomes a much better company in the future. They went from having great products to downright creepy and it’s difficult not to use any of their products or to be tracked by them. I’d like to see a different Google.
If you split all datacenter operations into separate company (Alphabet Cloud), Search and Ads will not receive access to cheap resources on significant discount, but will pay fair market price, which is a big burden for other companies trying to enter the market.
