Wouldn't a better model be to not charge the user for that month if they haven't watched anything? So you would only pay for months where you actually watched things on Netflix, and you wouldn't find that your account was suddenly deleted.
Also, maybe the title should be "Netflix will delete the accounts of customers who never watch", because that describes what Netflix will be doing more accurately.
They will be keeping the account data, so you don't need to start from scratch if you sign up again. It's more of an account freeze/deactivation than a deletion.
