They have the right to license the software while protecting themselves from liability issues caused by people who think they know better than the manufacturer as to how the equipment should be programmed for operation. They're the same people that will engage product liability lawyers to sue the manufacturer because they were, apparently, not protected from their own stupidity.
The manufacturer is trying to protect themselves from that type of liability. Because, in the end, the manufacturer doesn't pay the cost - the buyers do.
I'm not buying that argument. John Deere can include a waiver for tampered software in the purchase/warranty agreement just as easily as it demands a perpetually open credit card authorization.
far as not owning your own land, who is going to stop you from putting in a garden, or planting lawn over a garden, or cutting down an apple tree, or cutting the lawn.
this "software" con would require permission from, and a tribute paid, to John Deere for everything except fueling the tractor (for now).
far as buying another brand, if John Deere can find enough corrupt politicians to pull this off, other corporations will see the fabulous profits it generates and do the same thing. you will be paying full purchase price, plus rental costs, for 'your' tractor, for the rest of your life, and you won't have the option to vote with your feet because every other manufacturer will be lined up to suck your blood in the same fashion.
and btw, the argument that the government collects perpetual taxes, therefore it is okay for a corporation to usurp the authority of government and start it's own perpetual taxation program, on top of what the government already charges, just doesn't wash.
John Deere has no right to arbitrarily assume the authority to collect taxes.
I'm not a John Deere owner, but I am genuinely worried about this enormous overstepping of authority spreading to other manufacturers, because it will. :2cents:
