This is not a case of a company that does something massively useful but then does a (relatively to the size of the company) small illegal thing on the side. The whole raison d'etre of Tropic Haze LLC is to, allegedly, break the law.
Meanwhile, fair use is also a thing. I'm not real clear on where that illegality of bypassing DRM schemes fits in with that, and also how it fits in with other laws and exceptions.
So yeah, it'll be interesting to see what the judge says. :)
