Ok.
If you have ever been involved with an organization that has more than three members, you should know that there will always be conflicts between members. Always.
Since the Foundation has corporate members, and since corporations use the legal system to help resolve their disputes (much better than using guns, by the way) it isn't surprising that one member of the Foundation is suing another.
The fact that they both happen to be on the Foundation Board is, in my view, not terribly relevant.
It has already devolved to "corporate warfare."
