> Danfoss said the affected cold units were older models whose security software could not be updated to ward off a risk they had identified.

I feel like this is kind of holding the supermarket hostage and saying, “Sure your freezer is working fine, but if you refuse to buy new freezers from us prepare to get hacked.”

Sure you can argue that the supermarket should have just taken the old freezers offline. But you can also argue that the manufacturer could have supplied software updates but didn’t in order to force sales of newer models.
