We don't know what LAWS are on the books and if MS crossed the LINE. We don't know. Law is specialized AREA and even if MS tells you something which they can do, it doesn't mean it will hold up in a court of LAW.
Messing up hard drive is one area that I would like to investigate as to whether something you own can be dis-abled like that. I don't know and you don't unless you studied this AREA of the LAW.
MS has lawyers that were consulted at every step and they believe it would hold up in a court of LAW, but , who knows, taking them to court will let us know if it holds up.
Also, in cross examination would come up with method of checking they are doing. And hopefully the LAW firm will find people that were BANNED and shouldn't have been. If it can find a few people that were BANNED and can prove they didn't do anything wrong, that could have big impact on MS.
