Those are reasonable. A business must take account of its stock - a useful thing is happening. A TV station shuts down in the evening as paying for electricity to broadcast and humans to schedule programming that goes unwatched is unproductive. It is not reasonable that a piece of working software in a product I paid a substantial sum of money for, which has no good reason to not work, should not work randomly.

That is an external service needing to do maintenance.

Not my own device on my own machine.

I don't remember a time my CD player on my car would stop working due to an update.
