Google's Spyware Principals
I don't know about Jason's laying the blame for all these spyware apps at the foot of Microsoft, but I do agree that Google has done us all a big favor laying out "best practices". Someone like Truste ought to grab these and run with them. If every legitimate software company followed these rules, we'd be a lot better off. In fact, if the Spyware removal applications agreed not to automatically remove any applications that can demonstrate they are in compliance with these rules, then the good guys who use software based downloading as a distribution methodology would be rewarded and the bad guys will suffer.
UPDATE: John Battelle has a long and interesting post on this topic.
