I guess you’ve been living under a rock and haven’t noticed the persecutions of folks making video game console modchips, John Deere fighting with farmers over who’s allowed to repair tractors (including an MOU that the media claims is “kind of” a win for famers, but nevertheless asserts that “modification of Embedded Software” is “illegal infringement” of John Deere’s intellectual property [sic]), etc.

Sure, nobody’s gone to prison for “jailbreaking” (which is already an absurdity that should never have become necessary in the first place) a car yet, but the DMCA Anti-Circumvention Clause is still the law of the land and unless that changes, it’s only a matter of time.
