So much for your $1000 TV that had Netflix and only Netflix builtin, and will refuse to boot when the cryptographic check fails becaused you changed the string that points to http://www.netflix.com to http://www.notnetflix.com
But your TV manufacturer still wants to provide Netflix to other users and Netflix decided to require all their devices to run its trusted code if they want to provide Netflix to anyone, whether you in particular want it or not. So your choice is to trash your existing TV and track down a manufacturer that doesn't have any support for Netflix, Hulu, Youtube, Amazon Prime, etc. at all to buy a new TV that doesn't ignore your choice. With TVs you might be lucky since there is a large market for dump displays that avoid any TV related functionality anyway, of course there might be restrictions in the license between Netflix and the TV manufacturer to close that loophole too, maybe limiting sales of dumb displays to specific types of users.
Software is already here, particularly in social media (mastodon/SSB vs Facebook). That hardware eventually gets there seems to me an inevitability (arguably we're already at least partially there, as evidenced by the fact Purism/Pine64/etc exist).
I still don't see it as a problem, though, because an individual can have different technical interfaces (devices, OSes, etc) for different purposes.
Generally, I put my personal stuff on systems I understand/control.
For some things, like watching TV, I'm okay with going to Netflix because that transaction is expected to be transitory. If Netflix disappears or declares themselves a new world order tomorrow, I can simply unsub and no harm done.
Where things get problematic is when so much of someone's life is wrapped up in a mono-corporate cocoon (e.g. Amazon shipping things to your house and running your servers, or Google serving you search results + mail + maps).
