I don't think you quite understand the subject man. There is no monopoly. Now if you w an t to argue that tractors should use an obd2 protocol that is the same for all tractora jusy like cars. Argue that. But each manufacturer using their own protocols on their own products is not a monopoly.
OK, you seem to have some preconceptions of what I am talking about, so I will use OS to make a comparison.
Microsoft sells a rotten piece of shit OS called Windows. Lots of problems with it, but Microsoft tries to allow free downloads and updates to fix problems with it. Failing that I can go to THIRD PARTY VENDERS and buy tools to try to fix the problem.
Microsoft has a history of monopolistic practices but the Justice Department got on their case and they are more open with what they do now.
If I had to take my computer to the dealer I bought it from to update or run diagnostics on the software, people would be burning Microsofts HQ to the ground, and rightly so.
But John Deere is not ******* over 80% of the urban population that uses private computers at home. They are only ******* over farmers across the country and you are OK with that, I guess because you just think farmers should get fucked as frequently as possible.
Get it now, dude?
