Obviously I am biased, but my intent is to make a technical argument, not a sales pitch. I don't make any money from these (and I no longer have anything to do with protobufs). Protobufs was open sourced in 2008 (after being in use inside Google since around 2001). I suspect other binary formats prior to that had a solution for compatibility as well, but I haven't done a survey.
