Most people just want to be able to access media easily with no effort- which they already can do with cheap streaming subscriptions. They have no interest in owning the rights to use it forever, or in downloading or copying it. They wouldn't want to take the time to figure out how to do that, even if they legally could when they can already just click and play.
I think if you want people to care, you need to find a real world case where they are being blocked from doing something they really want to do- the abstract philosophical arguments about freedom are total non-starters.
Possibly an alternative media supplier that was fundamentally less hassle, faster, and more reliable because it didn't have these systems could get people to switch. But good luck getting the digital rights owners to let you put their content on your platform.
Or maybe convince people they can get higher quality media that way. I have a newish Mac with an amazing HDR screen, but few of the streaming sites are willing to stream the HDR content to my device.
