Nest Acquisition Eggs on Google Hate. Why?

The Verge raises a really interesting question: Why is everyone disappointed by Google buying Nest? Up until this acquisition, I think most tech nerds (aka non-normals) were pretty sanguine about Google, and were willing to trade some privacy for convenience (Google Now comes to mind). Certainly it's the case that Google was far more trusted than Facebook or even Twitter. At the same time, most tech nerds were hot on Nest. But, now that Google has acquired Nest, a lot of folks want to rip the stylish thermostats off their walls. The sentiment easily could have gone the other way, since Nest brings Google a user-centric and design sensibility it needs. Thoughts?
