Pretty soon, you won’t be able to own anything. Everything will be licensed. From the EFF:
John Deere is at it again, trying to strip customers of the right to open up and repair their own property. In the new License Agreement for John Deere Embedded Software [PDF], customers are forbidden to exercise their repair rights or to even look at the software running the tractor or the signals it generates.
The document purports to govern “any Software, data files, documentation, engine calibration tables, proprietary data messages, and controller area network (CAN) data messages that are in or communicated to or from any” covered product. Many of these items are numerical values that do not contain any copyrightable expression. The document forbids you to, among other things, “modify,” “reverse engineer,” or “reproduce” the covered information. These are necessary steps to understanding, repairing, and improving upon your equipment.
