Exactly. What I have found is that when I examine deeply enough, most DRM content is not even worth it, and even for purely entertainment purposes, there exist plenty of non DRM solutions: movie theaters, libraries, outdoor activities to name just a few. I found Michael Niedermayer's quote very nice in this regard: "Breaking DRM is a little like attempting to break through a door even though the window is wide open and the only thing in the house is a bunch of things you dont want and which you would get tomorrow for free anyway" (https://ffmpeg.org/pipermail/ffmpeg-devel/2016-January/18824...).

And if you really don't even want to accidentally support or open such DRM content, you can configure the browser appropriately (media.eme.enabled and --disable-eme in Firefox).
