That quote is an outright lie,you do get the option of not installing a couple of 'extras' but spyware is still installed without user knowledge.If you remove this crap from your system using Ad-Aware (Limewire advocated Ad-Aware not so long ago,probably as a cheap shot directed at Freepeers Bearshare) then Limewire ceases to function.
What's with the underhand tactics then? at least have the guts to give your users all the facts before they make the mistake of infecting THEIR system.
