All fine, but it is left conveniently unspecified what is meant by "reduce your rights". In fact, I don't even know my rights as I was not explicitly presented them in the form of a list in the first place, making the "reduction" ambiguous.

Admittedly it is not as easy to spin this as a more explicit ToS, but I am sure that with a sufficient number of legal experts, this has considerable leeway in terms of interpretation.
