I think it could be interesting to see Chrome sold to ten or more different entities. Allow none of them to use the Chrome name. The last thing Google can do with Chrome is have it randomly select one of the new variations for updates.
The DOJ / FTC / W3C / SEC / whomever vets all of the entities purchasing a share of the Chrome userbase. Part of the purchase agreement would be to have the update and development infrastructure in place and commit to updating their version of the browser and making good faith efforts to adhere to W3C standards for the next 3 years.
Once the sale details are finalized, Google pushes out a final update that changes where the next update to Chrome would come from (and it would be a random selection from the list of buyers).
Let's give Chrome to a million different entities, for free. None of them can use the name. We can remove all the Google add-ons as well. Call it something like... Chromium?
