I have a Mac Mini hooked up to my TV. We never use anything mode of the TV. (Then again, I have zero streaming services, so perhaps I am not who this article is for.)
Neither do I, but what about YouTube? Not letting your TV manufacturer sell your watching habits is already a big win, and on macOS you can further block telemetry. A big chunk of my YouTube consumption happens through yt-dlp using a VPN provider that presumably does not cooperate with Google.
Sadly, there's just a keyboard + trackpad sitting on my TV-audio console (a kind of home made speaker credenza I built years ago).
So no remote. I get up, hit the spacebar to pause/play. The audio is into a multi-channel receiver though so audio has mute/volume controls on a remote.
I have a Lenovo used minipc connected to mine and I just use a Logitech K400+, it runs Linux with KDE. I will never need a smart tv, or want one, for that matter.
I get that people would rather have a remote but I personally actually don't like remotes at all. My TV is basically a screen only.
