Chrome and Android are particularly interesting to me. What would splitting those projects off from Google possibly look like?
Both are open source projects with "ungoogled" options available, but those options are nowhere near as successful as the Google flavors. Would they just forbid Google from offering their own flavor of Chromium?
Even though Android itself is open source, Google Play services really are what allow Google to have so much influence on the Android platform. So what happens to Google Play? Would they be forced to split that off with Android? Would they be forced to continue offering their services for free, but with no strings attached? Would Android have to offer a middleware that lets you choose which services to use a la carte? Would Android device manufacturers have to ship their devices with an open source alternative to Google Play like microG?
How do you separate Google from Android without driving everyone to the other side of the smartphone duopoly, iOS?
If a breakup does happen, it's going to be wild. I wish I had more faith in our government to come up with the best solution. But something has to be done.
