Once,
I think the reason most shareholders are upset when there is massive insider selling is because insider selling almost always has a positive correlation with declining share prices. Insider selling is typically the event that marks the turn-around of rising IDCC share prices for many months to come. Of course just because it has happened that way so predictably in the past doesn't mean this time will be the same but it's a correlation that's too predictable to ignore.
I will grant you that there has been an uncanny connection between the two -- as you have illustrated.
But it exists only in the short-term.
Look at last year's insider sales:

Every one of last year's sales was at a price per share that is lower than today's closing.
I won't post the trades, but every one of the 2001 insider sales was at a price per share that is 1/2 to 1/3 lower than today's closing price for IDCC.
Obviously, there were some nice profits taken in late '99/early '00 -- but I think the point has been made.
