Wouldn't that work the same with an email a week before renewal day, saying "Hey, you haven't used the service most of this month, would you like to pause it before renewal kicks in ? We will let you reactivate it with a month free next time when you ask to resume."

That keeps the user in control of the situation, as a service you've been transparent, and you can still issue full refunds to users who come to you after a while explaining they actually wanted to cancel but forgot.

My basic POV in all of this is, the user enters the agreement on their terms, and it's weird to have the service acting cute and unilaterally suspend itself.

As a real world example, it would feel like leasing a car and have the dealer take it back during the night and stop the lease because you didn't drive last month. Sure you could just phone and they bring back the car, but why in the first place ?
