If it's any consolation, Redgate were the ones that locked down reflector. In fact Telerik released their own free decompiler as a response to Redgate's actions (though I haven't used it - the commercial version of reflector is rather nice).

Fiddler is a wonderous tool, yet in need of some UX enhancements, so I'm hopeful that this change proves fruitful for both the free tool and whatever Telerik ends up doing to monetize the product.
