Ripped web-fonts would not be very useful anyway, even if you deobfuscate them(it's just a simple xor encryption with constant key), because they're stripped fonts, so they lack the full charset. I don't see any reason to even obfuscate them since they lack the entire charset, but I think the reason MS did it was because of legal reasons(which is strange as the encryption is documented and someone doesn't even have to reverse engineer it, to be able to create something which reads or deobfuscates the fonts).
