I think the disagreement comes from the interpretation of "home" or "household". You might assume a HomeOS would operate all of your smart devices in your house or something like that, which would be fair. But if you think of the members of a household as being an essential part of it (which they are) then a HomeOS is also a fair description of something which operates on those members' behaviour.
