To be fair, up until recently copyright/DMCA prevented them from repairing the ice cream machines - I'd give it some time to see if things start to improve. Other kitchen equipment does seem to generally be fixed/replaced promptly enough to not typically cause major impact.

Sensors on the equipment seems reasonable to me. Predicting failure in advance can avoid downtime or more costly damage. Machines with degrading performance and some underlying issue can also be a food safety issue, if it isn't addressed until they entirely fail.
