> What's the legal basis of doing this?

I mentioned this in another reply, but I was imprecise with my language here. I meant that regulators could decide it's not OK for Google to have both a dominant ad network and a dominant browser. Discontinuing Chrome would be one remedy here, but there are also other remedies, such as spinning off Chrome development to a separate company.

As for the legal basis for doing that, I'm not as familiar with UK or EU law as I am with US law, but this was in response to the linked UK ruling by the CMA, where I was expressing my awe at how much effort they were going to in order to try to balance competing interests. I don't think regulators are dumb or lazy, but the report very clearly identifies that the core of the problem is that Google has both a dominant ad network and a dominant browser, but they still went through a lot of trouble to try to find a workable solution.

As for US law, Judge Jackson did rule that Microsoft should be split into two separate companies, one for the OS, and the other for apps, but was overruled on appeal. However, that appeal was muddied by other issues as well, and the case never came before the Supreme Court.

You're right about the US congress, but Europe does seem more eager to go after big tech companies.
