Google software/services going downhill?

In the last 6 months almost everything new that comes out of Google sucks. It started quietly with new and ugly Play design, end of several popular (or not?) services (Reader, Latitude) apps like Hangouts replacing Talk, that have both horrible design and functionality, Google Music with poor interface and data consumption, that was far worse than competition.

Last Maps update that removed offline mode and screwed up whole navigation (for me at least) and the new web Play store was just coup de grace.I could understand end of life of some services, but generally the quality of Google offerings went down.

So did something happen in Google during lat year? Some personal changes or what, with new people in charge of development? Because if so those people need to be fired ASAP.
