> Chinese owner .... inside people's homes

They made the devices. I would say its fair to assume they already had access to the data if they needed it. Other than the fact they legally own it now I don't think this makes much difference from before.

Why are you concerned about china having access to this data anyway? I'm far more concerned about how much access the US gov has to this type of data. They can easily use it against someone in the country they control if they want.
