This is my biggest issue with Google, past the immediate concerns about the Reader shutdown. Their new "focus" strategy sounds suspiciously like putting all their eggs in one G+ basket, regardless of whether it's a good fit for the problem at hand.
Spreading out lead them to create lots of good products that served all sorts of niches - the loudest outcry about Reader has come not from tech nerds, but from journalists of every stripe. Keep eliminating niche products, and soon enough it adds up to a large chunk of your audience, each of which had a different need that Google decided wasn't important enough to serve. There's value in diversity.
