I can't see any antitrust processes against Google going well.
The name itself has become a genericized trademark meaning "to look up information on the web." One does not say "I'm going to use Google to look for [Info]," they just say "I'mma Google that for you real quick."
And the thing is... Nobody except Google's business rivals wants that to change. Google is, at its core, a search engine. Years and years of refinement, advancements, and more refinements, have lead to it becoming dominant - because it is the best at finding what most people want.
I mean, really, what are regulators going to do? Block connections to google.com? As soon as people get over the initial panic of being unable to search for things and dredge up the vague memory of Bing and Yahoo (which I was surprised this year to learn still exists,) the first thing they'll do is search, using Bing or Amazon, "how to use Google in [country]."
It goes beyond that, though; gmail has become as integral to so many people's lives as Google web-searching. Google Docs/Drive has, too, and while everybody and their mother might offer webmail services, to my knowledge nobody offers what Google Drive does.
Any kind of serious anti-trust actions aimed at disrupting Google would lead to outrage and pandemonium. People's lives would be massively disrupted. Some people might even be outright ruined if, say, they can't get at their vital information on Drives or their Gmail. Android phones would all be in rough shape, too, since they default to the presumption of a lot of these services existing.
Like it or not, through a combination of being That Damn Good and some shady sneaky tactics, Google has become a vital infrastructural component of the everyday lives of more people than I can count. Actually knocking them down would be tantamount to political suicide, and might even lead to hordes of angry voters whose lives have been seriously compromised demanding a rollback of antitrust laws.
So what can be done?
I dunno. I'm not sure ought CAN be done. If they tried some cockamamie scheme to "split up" Google the way they split up Ma Bell, you'd just leave a bunch of orphaned services which are so interdependent upon one another as to be rendered non-functional. I guess you could, say, make a demand that Google set up their services such that you CAN choose to use other search engines to power the search bar, say, using Bing on the YouTube website search bar to search for videos...
But literally nobody would do so, because why the hell would you? What would be the point?
