Oh, I wasn't discussing the legality of it. Merely stating that if a major site (like Amazon) expresses concerns about it, Talk Talk are more likely to listen the them than they would you or me regardless of whether their actions are legal or not.

If I go to Talk Talk and say "Your actions are illegal, and I will block your users", they are likely to say 'Yeah Yeah", go on about their business and forget about me. If Amazon say the same to them, they are going to sit up and take notice.
