since the professed aim of the litigations was to 'educate' the public?"
Well, sure, but not to educate the public *too* much.
So often the message sent is, "you're educated if you agree with me." Truth does not mean very much to people like this. In fact truth, or at least the love of truth and the entire truth not for any agenda but for its own sake, was the first thing they had to sacrifice to become as sold to their own system as they are. The thing that (I believe) is often forgotten is that once people are compromised in this fashion, for any reason, they become "true believers" in whatever it was that compromised them and they give their allegiance to it. Most people are not entirely 100% themselves and are compromised in some way by ideas that did not come from a careful evaluation of available options. This is where the abuses and the underhanded maneuvers come from. That is, they come not from people who know they are doing something wrong and do not care, but from people who have an endless supply of rationalizations that they themselves believe.
