There's two sides to every deal though. You can't presume something is necessarily a worse deal just because on the other side you are asked to give up some right. You obviously must compare it to what you get in return. In the US you can waive much of your warranty rights with an "as is" purchase, for example. I think the important issue is whether it is clear to the customer or buried in fine print, which I do think is unacceptable.
