The excuse that the legal rules are obsolete is a red herring.
It depends on the rules.
For example: privacy of communications has no intrinsic dependence on technology. Security of personal data requires the verification of said security (or the commitment to it), etc...
I do not know about this specific law. But just because a law is old does not mean that it is bad. And this is what Microsoft is saying.
After hundreds of years of slavery, it was abolished in the US in a single day. So what? Is this bad?
