Yes, a common response is not to connect to WiFi, but I'm not 100% persuaded that it's a good answer. I don't connect my Kindle or some medical equipment to WiFi, but somehow they both (possibly Over The Air tech) are shared with the companies. Also, Amazon Sidewalk shares my bandwidth with others nearby against my stated wishes.
Are they shipping TVs with that capability, though? I understand a medical device needing cellular in case wifi goes down, but would they go through that effort for a TV?
