Some consumers would want complete removal of their data after deciding not to continue paying for service.
how about this - I dont use my cards that often - maybe 20 times a week. i'd be much happier if i got a notification through a side channel with a proposed charge and I could click 'yes' or 'no'.
it makes alot more sense to me than having to poll my account to look for potential fraud and argue with the bank about re-issuing a card with a new number.
wouldn't that be simple? i understand that for some usage patterns that would be inconvenient.
the broader point is that I shouldn't need to expose personal information just to buy a tea towel, I shouldn't even have to give you my email address so you can start sending my helpful hints about how awesome your other products are.
Secondly, I don't know of ANY company that deletes customer data upon cancellation. I've worked at a few ecom companies now, and the marketing team would just LOL at that idea. Past customers are pretty much your highest converters. No way are you gonna get rid of your data on them.
MAYBE in Europe with GDPR. Even still, no company I've worked at does this even for European customers. I'm skeptical a meaningful percentage of companies do.
