The real threat to Google will come when someone sues over this behavior as an antitrust case. This is part of "supply chain" antitrust law. It's sometimes called a "refusal to supply", where a manufacturer refuses to sell to a retailer. That's legal if it is not "part of a predatory or exclusionary strategy to acquire or maintain a monopoly."[1] If you're the only supplier of something, antitrust law starts to apply. That's basic monopoly law.
That's a can of worms Google would not want opened.
So few people understand this when these situations arise. We just need the right people with the right pockets and the right connections to DC to have such an issue.
The saddest part is that such behaviour will bring full power of regulation on all of us, just like GDPR did. Sooner or later lawmakers will come after all of us because of neglect of that sort.
