In mobile world there are only 2 DRM solutions widely adopted and they are: Microsoft PlayReady and Google Widevine. Jolla does not support neither of those currently -> So _NO_, there is no support for neither of the Digital Rights Management frameworks in the device currently.

If you think that DRM-term in mobile devices means something else then you have been eating wrong kind of mushrooms. All media files in device are unprotected and there is no Digital Rights Management frameworks device to protect media companies interest (well there are unix filesystem groups, but with developer mode its does not protect against malicious user). That is the current state of course if some media company makes native client for their media files, they might deploy their own DRM solution for example into TOH.
