I'm not sure. The courts intends for Google to sell Chrome, not Chromium. Even if they gave guarentees that Chromium will become independant, the coourt's likely to tell them to sell Chrome anyway (as they could still apply monopolistic practices like service bundling without control over Chromium, not to mention they could 'fork' LF's Chromium later to make their own).

The way I see it, this is more Google being scared shitless about Chrome's new owner being shitty, promote their own services instead of Google's, and disrespect web standards (or depecreates the 'standards' Google implemented in Chromium without the approval of other browers, or standard bodies). That could cause MASSIVE issues for them, and the loss of business that could cause would be tremendous, in a way that's far worse than giving up control on Chromium.

To me, his seems more like the nuclear option of Google saying that if they can't own Chromiulm, then nobody can as a way to cut their losses.
