Well, I should correct one thing:

There may be instances where the FSF would come to a different conclusion, regarding a particular case, when interpreting the OSD instead of the FSD.  However, in the (rare) instances of this happening that I have observed, it has not been very convincing and I doubt a judge would agree with it :-).  That is, I think those differences of interpretation on the part of the FSF may be politically motivated rather than logically motivated.
