There's been an increasing trend for manufacturers to restrict what consumers can do with the things they 'own'. So basically using DRM and other tricks to create vendor lock-in, boosting 'service' revenues, but harming consumers. But there's also conflicting legislation. So Dear John claims they need DRM to comply with emissions regulations. But sometimes that can conflict with common sense. So there's been a requirement to fit diesels with 'clean' systems like EGR (Exhaust Gas Recovery) and SCR (Selective Catalytic Reduction). That's supposedly good, but expensive, and reduces engine power & efficiency. Rather handy if you're in the business of flogging DEF/AdBlue though.
So it can be beneficial to 'delete' those systems. But then computer says 'no', because you've made an unauthorised modification to your.. I mean their property. Even if the modification means you'd still meet emissions standards. And then to add insult to injury, the EPA's been going around handing out large fines to anyone who sells services to modify or tune vehicles.
But such is politics. There's also been some fun recently with Peleton. They decided to change the software on their treadmills, ostensibly to improve child safety by adding a PIN feature.. But the update also means owners.. I mean captives have to subscribe to a $40/month 'service' to be able to use 'their' machine. Given Peleton's losses, I can see why they're wanting to lock customers into subscriptions, but it hasn't taken long for people to figure out how to jailbreak treadmills so they can carry on using them.
