There is a very significant difference between _monitoring_ the equipment and _controlling_ the equipment. I get it why monitoring the equipment remotely provides a number of significant advantages, I'm in data analytics. I do not see how putting control systems online gains enough advantages to outweigh the risks. Fridges in a grocery stores is probably a weak example, but similar incidents with power systems, hospital/healthcare devices, and the like can actually endanger human lives.
There was far more serious incident very recently where hackers gained control or attempted to gain control of a propulsion system of an oil tanker. Resulting in a military operation to take it back. People need to start treating these risks more seriously.
