I think people might be misreading a comment. To claim the laws are too "prescriptive" suggests that they try to handle privacy with a collection of very specific conditions, and should be amended to be more generally applicable (and therefore more useful as the underlying specifics evolve.)

To say that a category of laws should be less prescriptive does not mean that they should be "relaxed," but rather that they should convey their intent with minimal reference to the current technologies to which they are seen to apply.

Prescribe: to lay down a rule

Proscribe: to condemn or forbid as harmful
