Some people take security seriously by traveling light to China and Russia. An excellent routine is to erase the devices when you travel somewhere at all. Why carry all the important things that can get stolen? Keep it at home and take only the necessary – that is not only for security but a common sense too.
But you can get too paranoid. When the article mentions that “a thermostat in one of its corporate apartments were still communicating with an Internet address in China” you cannot help going like “yeah, right!” A healthy amount of paranoia is, well, healthy but this is taking the fear levels too far. Not to worry, soon your refrigerator will be reporting to China what you ate for breakfast back in California. Be scared.
