I think a lot of the anti DRM crowd (who aren't just into it for piracy) believe;

1. DRM works (or more precisely, it has gotten somewhat better at working over time).

2. It will proliferate to everything that can possibly have electricity in it.

3. In the long run this will lead to an authoritarian dystopia which will make modern China look nice by comparison.

By 2124, you will own nothing and you will be happy, or the Neuralink Assistant chip you were given as a kid will restructure your brain to "correct" this deficiency of happiness with your situation.

This is only half satire, I do truly fear this is the direction that improved information technology will move the political economy equilibrium.
