They probably just forgot to delete the subscription in stripe or whatever they use to manage it after the account was deleted? Sounds like a bug and not intentional? Can't imagine it is, they'd have to put more effort into customer service to handle the refunds anyway..
It’s a company with $200M in annual revenue. If they can’t afford to pay somebody to fulfill their legal obligations, they don’t deserve your contribution of pro bono PR.
I actually think some companies intentionally leverage this benefit of the doubt against their customers. No one would believe they would be architected to be hostile to their own customers, but that very well be the most profitable option for them.
