There's a difference between copy protection and DRM, although modern IP industries like to confuse the two as much as they can. Copy protection can be done by DRM or by other methods, and generally doesn't generate consumer ire. The moment DRM moves beyond that, whump, ire.
i.e. People don't tend to care too much they can't easily make 1:1 copies of their DVD videos. They do care when regional restrictions on disks stop them playing their disk.
The content delivery platform
Impulse is a fascinating study in this. It dosn't enforce DRM on items sold through it, but ties everything to accounts, which it will suspend if geolocation and frequency of usage shows clearly abusive patterns. This doesn't disable disk installs, it just means that updates, multiplayer and future downloads become unavailable. Even power users are
never going to bump into these limits.
