What we need to watch out for though, is whether they'll purchase a bill from Congress to reverse this decision. Congress continues to show it's willingness to deal with the highest bidder, and it's vitally important that either no law regarding spyware is produced - or if we must have one, it protects companies like PC Tools from being sued.
