>and there is no exemption to the DMCA for bypassing drm for personal or archival (unless you’re a museum) use
Sure, there technically isn't. But in reality, there's no practical way to enforce this without breaking much bigger laws. So very few companies care about some single person breaking DRM, if they are made aware at all.
The main exception would come from online games. But the "worst" retaliation you'd get is your account being banned. THey may not even bother sending a C&D despite companies technically being able to detect it unless you were cheating (which breaks the EULA, different from DMCA).
