I can understand if protocol buffers had some technical issue that you disagreed with. Or if you had a preference for a different solution because of some reason.

But this comment seems needlessly cynical and doesn't actually offer any rebuttal to the parent's point. I find technical discussions of these sorts of things interesting and a great way for new people to learn about the tradeoffs, maybe you could offer a reasoned opinion on why not use protocol buffers?

I think GP is making fun of people who do not use protobufs and instead try newer, less proven ones...
