Boston Dynamics always seemed an odd fit for Google give they were making robots for the military and Google has its "don't be evil" motto. I'm not sure how you bring those two together.
I don't know why people keep taking "don't be evil" seriously. It's obviously an effective slogan and somehow it's convinced a lot of people that Google is something other than a business, whose only purpose is to make a few people very very rich, but unless Google is legally bound to "not be evil[0]", it doesn't mean anything.
