You're missing things like (e.g.): - Tractors that have technical measures to prevent 3rd party repairs or replacement parts. Circumventing those measures is a DMCA violation, even if all you're trying to do is repair a tractor that you own without paying an arm and a leg to the manufacturer for a repair person. - Printer makers that use technical measures to prevent their printers from using 3rd party inkjet cartridges. It's not my fault that they want to use the "give away the razor, sell the blades" business model. - Basically any company that wants everything relating to their product to go through them, and to prevent 3rd party companies from creating replacement parts or performing repairs. The government shouldn't be making laws just to make certain business models viable (that are otherwise not viable). (e.g.) If you can't sell cheap printers without gouging people by selling expensive ink, then charge more for your printers. If printers are too expensive for everyone to have one at home, then so be it. They will do their printing at Kinko's (or the local equivalent). This works in other industries. Car manufacturers have had a 3rd party parts market for a long time (though they are definitely suckling at the teat of the DMCA and trying to make newer cars as locked down as possible). Do you really think that the US government should be making laws to shut down the 3rd party inkjet cartridge industry in order to protect HP's consumer printer business? Should the US government pass laws to make it illegal for a farmer to install a non-John Deere part on his John Deere tractor? Is this the kind of thing that the government needs to be doing?
