I bought a portable TomTom device a few years ago and...
...it kindly asks me to be plugged in to my pc to receive updates. It happens every 3 months.
Tomtom gently reminded me that this device is now too old and won't be updated any further. And my subscription is still active, despite having now no compatible device. Of course, it urged me to buy a new device, already covered by the subscription service. The now old device keeps asking me to be updated forever, and the tomtom pc software keeps warning me said device ran out of memory (2 Gib) and it can't download new maps, besides being no longer supported.
However, old device still works fine, much better than any android app currently on my phone, because it doesn't connect to the internet, not incurring in additional fees, while the GPS antenna is still excellent.
And roads on my Continent didn't change location recently, so I am perfectly fine with said outdated portable device and its outstanding ETA calculator.
And I expect the PC subscription to cancel itself (as in EXPIRE) when I refuse to pay for additional service, as I own a discontinued autonomous GPS device that is no longer supported by TomTom. And that's what should have happened here, the subscription should simply expire upon refusal of payment.
