I don't know if that is sarcasm, but a chair I buy is mine to do whatever I want with it. Same goes for clothes, a mattress, paint, or any other non-software enabled physical item. Why does having software/hardware make a difference?
That scene is dying a boiling-frog death. The newest OS that is fully jailbreakable on a sufficiently-modern arm64e device is 16.5.1 (go back a few models to the iPhone X and the current Dopamine beta works up to 16.7.15). There is also a "semi-jailbreak" called nathanlr, which is less full featured and works up to iOS 17.0 on iPhone 15 and prior. There's also TrollStore which isn't a jailbreak, but allows unlimited sideloading with arbitrary entitlements. This tool only functions on the following versions of iOS: 14.0 beta 2 - 16.6.1, 16.7 RC (20H18), 17.0
These OS versions are getting long in the tooth, and apps are already starting to drop support for them.
Because capitalists extend control wherever they can to maximize profitability.
If you want decisions that corporations make to be aligned with the desires of their users, you should be advocating for software/hardware built by consumer cooperatives.
