If a fix existed, then why didn't Danfoss have a fix?
I agree that they had a firmware update, but unless they had the operational capacity to update the checks notes freezers of all their customers, that is not a fix. The theoretical and technological aspects of solving a problem are often the easy parts.
It's like if NASA would claim to have a fix for the Opportunity rover on mars to get it operational again. All they need to do is to replace the batteries. Well, that is not a fix if there is no way to actually replace the batteries in practice.
I don't see why the existence of a firmware update would remove the culpability of negligence from the hardware manufacturer.
