Glad to you brought this to my attention. My proprietary vs OSS essay promoting hybrids was going to change OSS to shared source to avoid confusion of established OSS definitions. Now, I suddenly find Microsoft has a brand of intiatives called Shared Source. They had to pick the most generic, intuitive thing I could come up with. This will probably cause confusion at some point. (sighs)
Might get away with it but maybe need alternatives. If not "open source" or "shared source," what's a generic phrase for software that includes the source but not necessarily OSS principles.
