I do not understand why people can be happy with the artificial software barriers. I'm really happy with my Apple M1 but I'd never use it if I could not run Emacs and free software on it.
Cars, dumb TVs, dishwashers, etc. aren't general purpose computer platforms. There's no market for running arbitrary software on them, nor do they contain a web-browser.
Smart TVs, game consoles, phones and tablets on the other hand already are general purpose computers. It is possible for someone to run whatever they want on them, be it by jumping through all the hoops or just by hosting a website. These artificial software barriers exist purely as anti-consumer rent extraction; they don't limit the functionality of the device beyond putting a price on participation.
