If you think there is an issue, and aren't a developer, then simply open an issue in the issue tracker, and let the developers deal with it. Constantly repeating and making nonsense analogies in some attempt to try to force others isn't helping anyone.
There is no "Home" in this respect, and having NTP and a connectivity check hosted at an Ubuntu sub-domain are not threats to your privacy. If you think they are, then block the connections yourself on your own system and be done with it. Make merge proposals to make it more configurable. Do something other than just sitting here repeating the same tired analogy trying to force us into your point of view.
