What group or individual is going to slog through the work of getting this investigated?
What group or individual is going to slog through a lawsuit?
Would the EFF take it up, or is it outside their purview?
Is there any hope of reversal/fines/prosecution? Will it hinge on intent? Does that intent exist, or was ISOC just foolish? If there was intent, can that intent be shown beyond a reasonable doubt? Or is there some rigid, incontrovertible rule that has been broken, such that intent doesn't matter?
All in all, it seems like such a stupid financial decision by ISOC (and one which goes against their mission) that one can't help but presume some sort of foul play. But who knows, perhaps they just messed up.
