Modify car software
The companies lay out a parade of horribles that will happen if people can circumvent the DRM they put in their vehicles, mostly focused on the idea that people might soup up their car, making it dangerous. But that's not a copyright issue. People have always souped up cars, and before there was software in cars, no one argued that Ford could prevent you from turning your Mustang into a drag racer. It's only copyright that has rewritten the very concept of ownership in a dangerous way. As Kyle Wiens notes in his article at Wired in response to the "but, but, car modders!" argument:They’re right. That could happen. But those activities are (1) already illegal, and (2) have nothing to do with copyright. If you’re going too fast, a cop should stop you—copyright law shouldn’t. If you’re dodging emissions regulations, you should pay EPA fines—not DMCA fines. And the specter of someone doing something illegal shouldn’t justify shutting down all the reasonable and legal modifications people can make to the things they paid for. But, by far, the most ridiculous in the "parade of horribles" comes from John Deere who was really, really, really, really stretching to try to come up with some way to pretend this is really about copyright issues. It argues that allowing farmers to modify the software in their tractors might lead those farmers to (and I am not making this up), listen to infringing music while they farm. Moreover, TPMs for vehicle software for entertainment systems protects copyright owners of copyrighted content against the unauthorized reproduction and distribution of copyrighted works. For example, vehicle software for entertainment systems supports the playing of copyrighted music files and copyrighted audio books, among other expressive works. A vehicle driver may listen to sound recordings, while passengers may watch or view television and movie content. TPMs for in-vehicle entertainment systems encourage content providers to create and distribute highly-expressive copyrighted works that might otherwise be easily copied or pirated if the TPMs were circumvented. Consequently, circumvention of the above TPMs for purposes of “personalization, modification, or other improvement” is likely to encourage the unauthorized reproduction, distribution, and use of copyrighted software and content. I really feel sorry for whatever recent law school grad had this issue dumped on their desk and was told, "make this about copyright... some way... any way."
