> Why would they want to do that once they have separate owners? Because the established business model is proven to be super effective and all the organizations and infrastructures are already optimized for the such model? The real question is, why would they deviate from the existing anti-competitive behavior if reforming the "Google cartel" with business partnership will give them a roughly same level of functionality? You gotta understand that their incentive functions are already tightly aligned with each other because that's what network effect is precisely supposed to do, so it will naturally head toward anti-competitive regardless of whether they are separate entities or not. The only meaningful action to prevent that would be highly targeted and specific antitrust remedies.
