Anyway, Chrome has been terrible for the browser market. We used to have at least four major browser engines. Now we have three at most, but essentially one.
Chromium is an absolute pig of a browser engine. But then again, so is Android as an OS.
I think it would be extremely foolish to assume anything about what the DOJ will and won't be doing in the near future, given the changes it will be undergoing soon.
This certainly doesn't feel like something that is likely to be pursued...
