I think part of the goal is to have, in the record, a statement that any app that is otherwise legal but requires the user to download cryptographic keys to use is a de facto violation of the DMCA. I think that's why they're settling so easily here and likely paying the settlement for the Yuzu folks. They're hoping that they can use that as precedent for future cases.
It's also about the asset value of IP. Most if not all media companies have IP on their balance sheets. (Showing that you are) protecting IP is part of its value justification.
