Unless you want to join and wait 4-10yrs for your share of the "settlement" (which will probably amount to the low double-digit-dollars), while the law firm pockets a big chunk of change, why bother?
A couple of recent settlements I signed on to are even worse. Ticketmaster: the settlement in the CA suit against them made a lot of money for the firm, and the class members received....$10 off a future Ticketmaster purchase.
So, to get anything out of the company that ****-ed me over, I have to give them even more money. It effectively costs them NOTHING (apart from what the class law firm was able to negotiate "on my behalf").
Ummm - no thanks.
