I suspect that YouTube, being a closed platform that is not quite as integrated into the web the way search is will not be as much of an issue as Chrome and Android.
However, I am not sure that forcing a divestment of Chrome will achieve much. That is one element that Google actually built from the ground up and did not acquire. It was just so much better than Internet Explorer and Firefox.
I can see a bigger case for divesting Android. I suspect that Google might ultimately accept giving Android given that it has largely achieved its core objective of preventing a competitor search engine gaining market share by being the default in most devices.
The other remedy is likely to involve not allowing Google to post Apple for default placement, which may not feel as much of a punishment for Google in the short term given that there is no real competitor to take its place on Apple devices. It will just be a $20 billion annual saving for Google.
