Firstly, the design of application programming interfaces is usually not separable into free and proprietary software camps. Secondly, the commonly understood definition of "Unix" has come to include most API standards as they have come to be developed on unix-like platforms, such as networking, curses, long file names, dynamically loaded libraries, DES cryptography, posix threads, and the domain name interface (even if just considering the C interfaces). Consequently, you are exempting a very large amount of contribution to API standards to API standards without exempting anything from the other side of the comparison. Nevertheless, I think your slanted criticism is still false. If we define "Unix" to be just the base V6 unix functionality, then the entire history of the Berkeley Software Distribution enhancements to unix is a laundry list of counter examples to your statement. I am hard pressed to think of any standard from Motif (the HP Xray toolkit) and OpenLook in the graphics world to the domain name system (even if you just count the C programming interfaces) to C interfaces to extension languages like Tcl in which free software did not play a major role in shaping the standard. In most cases, free "reference implementations" were integral to the development of the standard, and often ended up obviating the need for proprietary versions. If there is any particular strength in documenting C programming interfaces on the part of the proprietary software world, it is because there is little alternative when the source code is not available (I am ignoring proprietary software for which source is available, because I think that is a statistically insignificant class right now). On the other hand, if you look at all programmatic interfaces, not just C calls, but also protocols, languages, utility programs, and maybe even file formats, I think the contribution from the free side is greater, even without scaling to the vastly smaller amount of revenue currently powering the free side. Examples from the internet RFC's are legion. Just to take a few that Microsoft has had to adopt recently, consider MIME multimedia email formats, the domain name system, and RPC. The contributions of CERN and the W3 consortium to the current web standards should not be overlooked, and, by your definition of "free software", I suppose you could throw in contributions due to Mosaic and Netscape.
