Does it take the view that I encourage/facilitate illegal use of my product unless I state otherwise in the T&C?

Encourage, probably not. Facilitate, possibly. That's why my bottle of Windex glass cleaner says "it's against federal law to use this product for anything other than its intended purpose."

In either case it's illegal for me to use it for bad purposes, but how much I can blame on Windex depends on how much they let me know that I shouldn't do bad stuff with their products.

Ask every account that has ever released information on drug use, lock picking, explosives manufacture, or "hacking" - they all say "for educational purposes only" for a damned good reason
