This antitrust lawsuit Google just lost is good, but man I hope they don't fuck up the punishment.
Android is open source. Each manufacturer has its own flavor of Android. Breaking it off from Google just to stop Google Search being the default engine doesn't make much sense.
As an example, Google owns Android trademarks and some patents and those are used for leverage in search negotiations. The court could just turn them into some type of public domain assets. The leverage goes away, but so does revenues of any potential Android Foundation.
