While I agree with the sentiment, let's just go down that list:
- Where he lives: DMV and taxes cover that
- What he looks like: DMV covers that
- How many devices are on the network: The vast majority of people have no reason to care about that. Hell. I am not even sure I are about that
- How many kids he has and their ages: Taxes and social security
- What times they are home: Their internet usage patterns and likely cell towers logging their sim cards
- What types of food they have delivered and how often: Traffic cameras and asking uber eats or whatever. Although... this goes back to "how important is this data?"
- Guest info: See above regarding sim cards
I 100% agree it is important to be aware of what data a given device/vulnerability has access to. It is ALSO important to figure out if that is actually any new data being available and to think about what orgs/agencies would be a concern.
Because maybe you DO care about the principle of it (I know I do). But "It is the principle of the matter" is just as ineffective an argument as "I have nothing to hide".
