That said, I think John Deere is just the asshole willing to weaponize the legal system to enforce their dreams. The real problem is laws that protect IP like the DMCA and the patent system. I'm not saying we should just delete all those, but they are in bad need of reform and enable a tremendous amount of abuse. The abuse is only going to get worse unless we treat the cause(s) rather than just the symptoms.
I'm glad the feds are giving John Deere some attention, but I really hope they are going to fix the lopsided system instead of just try to bully or micro-regulate John Deere into "voluntarily" allowing more repair. If we stopped unleashing the lawyers on people for modifying or interfacing with devices they purchased, it would shift the balance of power more toward the center (whereas currently the power is almost entirely on the side of the companies).
Even if you have no interest in repairing or "tinkering" with your own stuff, you should be on the side of right to repair.
