Indeed DRM is a very different thing from adhering to standards like `robots.txt` as a default out of the box (there could still be a documented option to ignore it).
He was using DRM as a metaphor for restricted software.
And advocating that software should do whatever the user wants.
If the user is ignorant about the harm the software does, then adding robots.txt support is win-win for all.
But if the user doesn't want it, then it's political, in the same way that DRM is political and anti-user.
