Let me ask you this -- why in the world do the lines of software you write prevent a qualified mechanic from changing a transmission? You know people used to do that all the time when tractors had zero lines of software in them.
After all you are trying to very cleverly change the subject here. You are doing it very deftly, as you should, because you are not a software developer, you are a PR drone and it is your job to deftly change the subject.
The question here is not about the quality of the John Deere software, so it does not really matter how many engineers worked on it or how hard they worked on it. The problem is that the John Deere software takes away an essential right of property ownership that people take for granted.
No one is accusing the JD software of being faulty, i.e., incapable of serving it's intended purpose. People are accusing the software of having nefarious purposes and serving them all too well.
