Sure, the temperature should just be logged automatically to the database, and the value shouldn't be allowed to change. However, it isn't. And I can see clearly how a database supplied by some vendor would yield to pressure from a government to 'tweak' some value, just this once, so that they'd be sure to get a nod on the next contract. I would trust a public ledger on its immutability more than a government run database. Or a maintainer of a database that relies on government money to exist.
