Huh. Interesting, I don't know how to feel about this. The idea makes sense, and I like that "Google" is going to be for search, and that this change shows how many different areas Google/Alphabet is in. It will take some getting used to, for sure, but I think its fine in the long run.
Well, I also suspect part of this is trying to dodge monopoly battles, just because of how large Google has gotten as a company and how much of the market they control in various areas.
