I doubt any TV company will ever do this, for two reasons. The first is simply that it would be obvious due to FCC filings. The second is that 99% of their customers hook their TV up to the internet so they can use streaming apps on their TV. They're very unlikely to eat the cost of putting a cellular model in every TV, take the PR hit for doing so, simply to capture the ACR data of the 1% of their customer base that is most likely to figure out another way to disable it.

Whereas your CPAP machine is likely a high margin device and the reason it has that modem is because insurance companies require compliance data in order to continue providing coverage for replacement supplies. Resmed or whoever is happy to bundle in the cost of the modem + service in order to keep selling high margin supplies.
