This is the actual reason there was all that hysteria around the "race to 5G" with the dire warnings that we'd be buried by China if we didn't roll out 5G ASAP. The actual reason is that 5G works better with congested cells and large numbers of clients than 4G, so it's a lot easier to put cellular modems in every device and bypass those pesky users.

Except many TV models are already sold at a loss. Throwing a $20/month cellular modem in there isn't going to help any.

The number of users who opt out of connecting their smart TV to Wi-Fi is so damn tiny that it is a rounding error for TV makers. They just don't care.
