What you're saying is beyond misinformed.
Sky don't prevent you from torrenting or restrict speeds on p2p or anything else for that matter. Every single UK ISP is subject to court orders from rights holders, Sky was one of the few who went to court and argued for it's customers rights repeatedly at every available level domestically, others gave it up without a fight. As to the UK domain blockade against certain sites it affects Sky, BT, TalkTalk,VM and others, you'd have to be living under a rock not to know by now how easily it's avoided. Ironically despite being owned by BT, Plusnet haven't joined yet but it's probably only a matter of time.
Go and research VPN's or cloud based p2p services if you wish to avoid the world knowing what you are downloading (legal or otherwise), but don't slate the very ISP's who should be congratulated on taking a stand even when users are naive enough not to protect themselves.
Oh and BT's Quidco is usually better at the start of the month than the end, they adjust it depending on how close they are to target.
