So point one falls into the domain of intellectual property vs simple copyright, which most open source developers simply want to ignore. As far as I know, and based feedback from any lawyer I have worked with on this topic, the reality is that there is no open source license that is sufficient to handle both copyright and other intellectual property rights such as patents. Any purely open source license based foundation is relying on corporate members with patent portfolios providing defense grants to not be prey of patent trolls. I am interested in the OASIS open source based spec process that IBM is scheduled to present this week at our weekly call to understand how this has been addressed.
On the second point about fungibility of corporate spec representatives equating to a bypass of the meritocracy rules, we should simply make a point of calling out that "representatives" on a spec are based on demonstrated expertise/meritocracy, and any exchange expects that to be maintained. This would apply to exchange of corporate or individual spec representatives.
