Google has had a strategy of keeping some parts of Android open source for the benefit of the world, and other parts closed source inside Google Play Services. However European regulators continue to rule that Google Play Services itself is the leverage Google uses to lessen competition. If regulators have antitrust concerns with just one proprietary blob, there's really no incentive to make Android truly open. Opening up the rest of the Android literally doesn't help with antitrust.
