Yep. But, for Google, that's just reality. Either you're Google-scale, or getting there, or (walking) dead. And I get that, they are operating a business, after all.
For a sense of scale: Android has about 3 billion users. When working with products like that, something that has 3 million users is a rounding error. G+ now probably has less than 3 million MAU. So if a product like that has a potential to cause (PR) trouble for all of Google, well, the incentive to shut it down is pretty clear.
I do not like it, but I understand it.
