While I get your point, the TV isn’t nice because of its app features. If it’s a nice TV it’s because of its display panel and features like upscaling, interpolation, etc., and it’s being subsidized by those built-in apps and tracking functionality.
By purchasing a nice TV, never using the built-in apps, and never connecting the TV to the Internet (or better yet connecting it to a segregated VLAN and dropping literally all traffic to/from the TV), you’re costing the company money on that TV set. Or probably more accurately you’re like the credit card user that maximizes their point rewards while paying off the balance every paycheck, you’re profiting off people who are in debt to their credit card company for whatever reason.
To be clear, I have a G series LG OLED that is not only in its own VLAN with no traffic allowed in or out, but I drop all DNS that isn’t coming from my pihole at the WAN port on my edge router, I watch stuff from a secondary device, and most everything I watch is pirated and streamed locally anyway, so I’m definitely subsidizing my entertainment with the privacy invasion of others. If I could get an OLED tv without any of the built in OS stuff I absolutely would, and would be willing to pay more for a SKU with that stuff stripped out, but afaik that’s just not possible.
