Researcher in article discovered that oven pings google , yandex and baidu to check if internet is present.
I think who ever coded oven firmware was fair because oven connectivity data will be equally shared with all major sides.
And also resilient, if it was only google, or only baidu or yandex, then they would have too much power to control the ovens. For example google may not respond and oven would never enter "internet present" state.
... Or they could just code different firmware for each region.
