Why? (Genuine question).
Google is just some corporation, and one that’s been drifting for the last 15 years or more (since Schmidt left). They are not even a good actor, yet (and I don’t blame them for this) have sucked a lot of air out of the ecosystem.
Creative destruction is one of the key values (-> leads to benefits) of capitalism, and with US & EU antitrust asleep at the wheel we should be glad if Google is ground to dust and replaced by somethings (plural!) better.
