The reason to complain for the other commenters is that you're criticizing something you've never used, while being familiar with only one method of doing things.
Who said I've never dealt with malloc or ARC (which I think is ill-suited for concurrency)? I basically replied to the OC, giving some good reasons for developing better GC strategies for a language with great support, libraries and a vibrant ecosystem, rather than moving to the next shiny thing. We're developing a latency sensitive real time bidder and I'm more than happy we can do it in Go now, just like the rest of our APIs, thanks to Go 1.5
Your criticism is not legitimate.
