Not sure I agree... at least not completely. For the way I interact with my devices and services, Google has made things much more efficient and greatly refined the UI's to eliminate most of the junk I couldn't care less about from my daily routine. I literally sometimes go check the "Social" and "Promotions" folders in G-Mail sometimes when I'm bored, and I'm grateful that the contents of those folders are not displayed to me unless I go seeking them. Of course, the usefulness of functionality and the pleasantness or lack thereof of a UI, etc. are all extremely subjective, but generally I like the direction that things are going, if I do second guess quite a few of the individual decisions, taking a step back and peeking at the larger perspective is rather reassuring.
One of the things I have a love-hate with is the reductions of customization abilities within Google's services. It used to be a tinkerer's dream to get Google products and customize your heart away, make each and every thing your own. As Google evolves and unifies their platforms, a lot of those options are going away. At the same time, I'm getting older, busier and sometimes really appreciate having a rock solid place to start from, without HAVING to go "fix" what they left undone. Although, I don't think I'll ever stop loving the ability to take that starting point and then finding ways to make it me, I generally agree with the design philosophies represented by Google and am excited to see where it's going.
I know people can find change difficult to deal with, especially if you really love something in it's current state... but maybe it's the timing or just a personality quirk, but I feel like Google and I have been growing up together and I'm pretty amazed by some of the things that I see coming out of there. All that being said, sometimes it is a little old constantly beta testing each thing and having them evolve at different paces and sometimes it's really easy to appreciate the polish that people love from other companies.
