Unfortunately, our society (and, particularly, the lack of meaningful regulations regarding how complex the process of canceling a subscription is allowed to be) has trained a lot of people to believe that it's going to be extremely difficult to ever get a company to voluntarily stop billing you every month. Netflix may not be guilty of this, but enough other companies are, that it's what people *expect* based on their past experiences.
I came to the comment section on this story, expecting people to be talking about tactics like opening an account with a different bank and closing the old account entirely. It didn't even *occur* to me that the answer might be "click a red cancel button on your account page".
And, I mean, it's moot for me, personally. I have zero interest in Netflix, and also I don't use credit cards, at all. (I'm... atypical in some ways.) But Netflix actually making it easy to cancel, is not what I expected to read in the comments.
