I'm still nervously holding my breath for the first disclosure that a TV manufacturer is using Amazon's distributed Sidewalk Network (or perhaps mobile vehicles, cell-SIMs, LoRa) to remotely gather all that viewing data they've subsidized into your artificially-low TV purchase price .

But they've been calling "crazy?" for decades.

This exactly. Surely some sort of IoT mesh networking will allow exfiltration of data even without having configured your own device.

I'm hopeful that there will be sufficient distrust that "jailbreaking" or "rooting" TV controller boards will be turnkey enough to move to something like OpenWrt or GrapheneOS but for TVs.
