Pete Ashdown, founder of XMission (the first ISP in Utah) on Six Strikes, CISPA, and the Assault on American Privacy:
XMission support staff, although skilled at helping you with your Internet problems is ill equipped for judicial matters. We believe that law-enforcement, when equipped with a constitutionally-required warrant, is best for investigating criminal matters. XMission will cooperate with law-enforcement when they present a proper warrant.
Outside the terms of law-enforcement with warrants, XMission cooperates with no third parties when it comes to the privacy of our customers.
Seems like a simple and common sense approach. Would be nice if more ISPs had similar policies.
