If you are concerned about a contribution of yours that is present in one of the recently released archives, you should take it up privately with the foundation. If you are planning to use or create a commercial product, a review with your attorneys is strongly suggested. Otherwise I don't see a lot of value in the discussion.
Seems to me that there is always going to be some non-zero risk of lawsuits when making a change like this, but clearly the foundation was comfortable with the risk. So what's the point of this discussion? Who are these disgruntled contributors you are speaking on behalf of?
