At the risk of courting controversy, I'll confess that I haven't even so much as considered using Golang on the basis that it's a language ostensibly controlled by Google.
I have reason to believe that my moral stance against Google is shared by many in the development community, but I don't recall ever seeing this sentiment extended to Golang.
The anti-Oracle sentiment is thick and heavy in the development community, mainly surrounding Oracle's predatory business practices and how they leverage them via Java. I've completely avoided investing in Golang for that very reason, I don't want to ever become beholden to Google's services in order to maintain further development in this language.
