I would agree with some of the assertions that yes Google is still Google and Alphabet seems almost non-present but I don't know if they have finished their integration / breaking apart of groups or really much of anything. I still think Android and some of the other parts of Google should probably be split out but I have no idea if that's the best choice for them or not.
I would love some more information on the whole formation of Alphabet. This, unfortunately, is not that article.
Can you give some examples? I'm mostly interested in what Android has compared to iOS?
It would be interesting if they explored it at least. In my opinion anyway.
So yeah, that would be difficult to split out.
It also integrates results from Dailymotion and others. YouTube would probably be the easiest property to spin out if it wasn't for the interest tracking data sharing.
Same with Youtube, Maps, etc. They exist to preserve the dominance of and prevent other companies from avoiding Google's key moneymaker, which is ads on searches. Thus allowing them any real independence would destroy their reason for existence.
