Well you could stop blindly following such a strict definition of free software.
DRM is hear and it is going to stay.
Why?
Back in the analog days. We had tape for VHS. Sure you can copy it. But after 2 or 3 copies of copies the quality degrades. So to mass share VHS movies ends up being costly with poor quality over generations.
Then we had CD's where at the time they held more data then you could really fit on your drive. So you had non-DRM data however because you couldn't store it on something other then other CD's which were costly in themselves. As well would take hours to download.
Today with the internet and modern computers we can ship and store massive amounts of data there. In Economic terms digital data has nearly infinite supply thus making its cost to $0.00.
However to make such data costs money, so safeguards to artificially limit supply to keep prices higher are implemented aka DRM.
Now what would happen if there wasn't DRM.
Netflix would still be shipping you DVD in the mail, you will have to buy all your music on CD's. They would probably even stop CD's and push Records or Tape. As to prevent digital copying.
The fact that for $10.00 a month you get unlimited movies off of Netflix is actually a big gain. And we have to thank DRM for that. Otherwise big companies will not go digital as it will produce too many units and they would be giving it away at a cost.
