I highly highly doubt that DOJ succeeds in convincing the Court to force Google to divest Chrome. That wasn’t really part of the trial, which focused on Google’s contracts to make its search engine the default on other platforms.

However, if DOJ does succeed then yes this case could make it easier in the future to force Microsoft to divest Bing if Bing ever gained a monopoly in search. As a comparison, the original Microsoft antitrust case precedent is very important to this search case. That’s why the government sued in this district (the same district they sued Microsoft in decades ago).

Microsoft/Bing is not the dominant (far from it) search/ad/platform provider
