I've only made cursory searches for dumb TVs, but I'm certainly aware they're tough to find and very very expensive. I just hope I don't *need* a new TV before I can afford one I'll be happy with.

I've missed most of the creepy stuff from Roku. I run a pi-hole on my network which the router passes *all* my traffic through and that seems to be successfully blocking my TV from phoning home to Roku's telemetry and ad servers. I highly recommend setting up a pi-hole if you have the means and the spoons to manage one. It does a lot more than just block Roku tracking.
