99% users won’t ever need that. For cases when they do, they can find guides, modify settings or install software that does what they want.
You could make the same excuse for Windows.
Any distro you download can do this exact thing and you wouldn’t know for a long period, unless you spend enough time to compile the whole thing yourself, compare and research.
You don't have to compile to know this. You can find the list of fully free distros here: https://www.gnu.org/distros/free-distros.html . Debian removes those blobs too, but it's not on that list for other reasons.
I consider myself knowledgeable but you surely chose a wrong example to teach people about DRM. Try some denuvo or eac maybe.
That's DRM too and there are many more examples. Blu-ray also contains DRM. And so do most PC games thanks to Valve. Console games on the other hand usually don't have DRM when you buy a physical copy.
Whatever that means, users don’t care about it. Compared to others, Valve provides a lot more value in most of their solutions. They are hackable just enough to satisfy most enthusiasts.
I know that most people don't care about their freedom, privacy or security. Most people use Windows. But this doesn't stop us from trying to build a better world for ourselves and to try to convince others to care.
