It does make some sense at that scale.

If you're managing 800 freezers, not only would you want statistics like that to catch any malfunctions, you might want to be able to control temperature or defrost cycles just for efficiency reasons.

They should be properly secure though. Infrastructure like that should only be accessible over a VPN while using a company managed computer.

Guaranteed there was someone in IT that flagged this as a potential risk and was told it would be too expensive to correct. Now there will be a push for inproved security for a couple months before middle managers start seeing all this unnecessary spending eating into their bonuses.
