They come up with tons and tons of products like Google Glass and Google+ and so on and immediately abandon them. It is easy to see that there is no real vision. They make money off AdSense and their cloud services. That's about it.

Google does abandon a lot of stuff, but their core technologies usually make their way into other, more profitable things (collaborative editing from Wave into Docs; loads of stuff from Google+; tagging and categorizing in Photos from Picasa (I'm guessing); etc)

It annoyed me recently that they dropped support for some Nest/Google Home thermostats. Of course, they politely offered to let me buy a replacement for $150.
