Hmmm, let's see, how much money does MS make a day? Even the Neo people feel it's fine what they are doing, small peanuts for MS to bring lawsuits against them anyway and bury them in legal fees.
First impression if they wanted to, it seems that MS would probably invoke the DCMA to try and stop it, since that seems to be the most effective attack these days.
We've discussed this type of thing before, and there is no way I am going to participate. It's one thing to use DC to crack an encryption key that has no real world value, it's quite another to go after one that allows bypassing security features of a corporate product.
