And how will selling Chrome and then Google forking Chromium and Google employees continuing to submit patches and/or developing the fork fix anything?

Is the DOJ going to forbid Chromium from accepting Google employee patches and forbid Google from using or forking Chromium? What if someone else forks Chromium, will Google also be forbidden from contributing to or using that fork? Is the DOJ going to forbid Google from using any web browsers?

P.S. the Chromium organization is controlled by Google, which is separate from the Chrome brand/product. Is the DOJ also going to force Google to "sell" or divest that?
