The DOJ is asking the court to force Google to promptly and fully divest itself of Chrome, along with any data or other assets required for its continued operation. It is essentially aiming to take the Chrome user base—consisting of some 3.4 billion people—away from Google and hand it to a competitor. The government will vet any potential buyers to ensure the sale does not pose a national security threat. During the term of the judgment, Google would not be allowed to release any new browsers. However, it may continue to contribute to the open source Chromium project.
I don’t see anything anticompetitive in that. Many browsers use Chromium because that’s what users apparently prefer. Look at the history of Firefox’s market share or the market share of the original Edge. Users had those options and rejected them despite the fact that the former had an enormous head start and the latter was bundled with Windows.
Many browsers use chromium because it’s cheaper and easier to bundle blink than to roll your own
Even Microsoft couldn’t compete against Chrome and abandoned their own engine.
