While I agree with you, the traffic to China did stand out in my router log enough for me to notice this. Had they used Amazon Aws, I might have never investigated.
Plus, this is how I learned that Phillips is just a brand of a Chinese company now.
And where the regions do get relevant again is for the legality of it. If it's an EU company doing such data extraction, they would be swiftly punished for it. Same I presume for the US. So I would assume that they are using a Chinese intermediary for the data to avoid / delay the legal consequences from it.
