The DRM thing unfortunately has nothing to do with EVs and everything to do with the computerization of cars. All cars have gotten more and more computerized and harder to repair with more DRM. EVs arguably fundamentally require heavy computerization more than ICE cars, but you're not gonna avoid it in a brand new diesel car either.
The EU did put in regulations, but they did the opposite and essentially mandated DRM. They want to prevent owners from turning off nanny devices or overriding pollution controls.
