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.
