That's nonsense though. Facebook shows up in search results too. I see where you're going with that, but it's invalid.
I like Google+ and SPYW, so I can only speculate. But, since I work for Google, it's important to me to be able to understand what complaints users have about our products.
People frequently dislike change, and so I'm pleased that a major company such as Google has the will to change and improve it's services. But they not only improve their services, which is good for their bottom line, but also releases a lot of their work and research which helps others.
