> Whether DRM-based price discrimination "allows the manufacturer to sell the device at a lower price point" or allows the manufacturer to sell the device at a premium price point is the heart of the dispute. You can't know whether it's one or the other without modeling whether the contrapositive hold
You're making this more complicated than it has to be. You can easily know this by just looking at the capabilities that other tractor manufacturers are offering at the same price.
Like he said, there's no monopoly in the tractor business. And it's not like someone is buying a fake Gucci bag by accident. These are $100,000+ purchases with a lot of back and forth. You know what you're getting into and you've presumably shopped around to look at a ton of alternatives.
There doesn't have to be a monopoly--competitiveness isn't binary. Intel doesn't have a monopoly in x86, and yet Intel uses firmware to cripple their chips (e.g. certain instruction sets disabled on low-end SKUs) while AMD doesn't. But does anybody really think that the x86 market is as competitive as, say, shampoo; or that Intel's price and product discrimination is resulting in lower prices at the low-end than would otherwise happen?
Maybe, but it's not immediately clear. And in any event it would be foolish to take Intel at their word that their strategy results in lower prices and/or better products, regardless of their sincerity.
And FWIW I'm not claiming that John Deere should be prohibited from doing what they're doing technologically, not unless it rises to an anti-trust violation. However, I do oppose the abuse and extension of copyright to prevent reverse engineering and prevent owners from modifying their machines. Even if John Deere's strategy is resulting in lower prices at the low-end, I'm not prepared to sacrifice the ability more generally (in this and other markets) for reverse-engineering competitors to sell their own firmware. There are many other reasons beyond the threat of copyright lawsuits why customers wouldn't want to run a machine with adulterated firmware, so even if a robust reverse engineering market resulted in higher prices for these particular tractors, it'll likely only be marginally so. I don't think it's worth cutting-off potential competition at the knees for whatever gain John Deere is claiming. History has shown that such policies, writ large, are extremely detrimental.
