I don't understand. Why isn't the AppleTV implementation of AirPlay and Homekit sufficient, rather than through a TV OS? Apple TV is far superior, and more secure. I suppose there may be a limited number of scenarios for specific Homekit control of the TV, but it seems minimal. "Smart" TVs are the dumbest piece of technology out there - there's little use case for consumers. The manufacturers just keep pumping them out to try and infiltrate consumer homes with their versions of spyware and malware through the TV.
