It's a mixed thing. Good for reducing piracy and increasing revenue, probably. It does mean that people who want to be able to install whatever they want on their devices, or write software for themselves to use on their own devices, will have to start buying ones explicitly marketed with those features, because you won't be able to just jailbreak it anymore.

Why can’t a manufacturer just decide that they don’t want people jailbreaking their devices? It’s a black hole of a use case to support, especially when there are plenty of open Linux-based platforms for power-users to hack away on

Why are you arguing? I don't have any control over what manufacturers do. I'm glad there are open platform equivalents, like the PinePhone and Steam Deck. I just hope businesses like that keep existing, or else there'll be no way for you to control your devices without building them yourself. It empowers manufacturers and disempowers the individual user, even though the law hasn't changed. That's why I said it's mixed, not unilaterally good or bad. Maybe it'll be good in the long run by making people buy from platforms like that if they want control, promoting legitimate business.

Oh idk just wanted to get the ppl going
