Well, Microsoft is contractually the ONLY founding member of their foundation, and the statutes define that the executive officer has to come from the founding member, and that every decision the foundation makes has to be approved by the executive officer. That setup gives Microsoft 100% control over the foundation. So, unless this new foundation's statutes grant special privileges to AWS - they can't possibly exert the same level of control over it, that Microsoft has over the .NET foundation. If those 20 founding members all have some voting and veto power, then AWS can't make unilateral decisions. That's what my question was about - how is the foundation set up, and how much power does Amazon have over it? If the foundation is sufficiently independent from AWS, then we are golden.
