Worry about a class action suit, why? Just because some people made a poor investment, and dont think its fair. I never hear of anyone complain if a company witholds positive information for a while, resulting in a quick overnight profit. Class action suits were also filed against 3Com and Ascend this week - big deal. Its most likely to result in positive news to re-inflate the price, making the suit look like unneccessary sour grapes. Too many lawyers with not enough cases - they should get out and work for a living.
On the point, why do scientists use rats for laboratory experiments? Because theres some things even lawyers wont do.
