This seems to be exactly the bad thing that
https://www.gnu.org/philosophy/opposing-drm.html warned us about:
> If we allow companies to use our software to restrict us, this “open source DRM” could help them restrict us more powerfully and reliably. Those who wield the power could benefit by sharing and improving the source code of the software they use to do so. We too could read that source code—read it and weep, if we can't make a changed version run. For the goals of freedom and community—the goals of the free software movement—this concession would amount to failure.
