Interesting. Probably 95%+ actually do (for practical reasons) use their phone for commissioning - do they all onboard into google/apple cloud fabric automagically and then share it to HA afterwards? Does this result in all the matter devices “locally” connected/shared to HA actually permanently phoning to google/apple sharing their wellbeing/states?
Not sure where the myth comes from that apple (or amazon) wouldn’t cashify all their available data streams (matter? ) they have access to… I remember some old study and their was litteraly no difference between androids and iphones which both spying on their users massively
Disable device attestation in the HA matter server would probably lead it to directly loose certification because of matter specification violation
It’s actually very theoretic “owning” matter device
