>We don't currently block apps when subs are cancelled (except in cases of abuse) but we will likely do something in the future if a customer has cancelled their subscription but are still actively advertising their app on their site for example.

Actively seeking a method to stop your former customers from offering their finished product because they no longer see a need to pay for your service is a good reason to never use your service.
