I am pretty sure there is a business that can be built over managing all these subscriptions - something like European OpenBanking but that includes credit cards - and you just get a dashboard showing you all the subscriptions you have (that will be ticket shock) and then you can turn them off as needed. Not sure if credit cards are in openbanking but that would be the core of it
