The entire framing of this post is wrong anyway (unsurprising, since it's just content marketing slop). This isn't something that the DOJ just decides on. They're the plaintiffs, not the judge or jury. Instead it's the remedy the DOJ asked for from the courts.
And if they can't figure that out (hello Mozilla?) then the worst that has happened is we have a more even distribution of user agents on the web, and people stop coding for a single engine whilst ignoring breakages for the smaller players.
If so this celebration is a bit premature. In 2 months a different party takes over and I can see echos of 2001 and Microsoft here.
