I think the issue is assuming the company charging the account are behaving in a moral manner.
Changing terms after the fact, dark patterns, charging for things the customer didn't agree to, over billing for cable services in the hope the customer just doesn't notice or gets worn down by trying to fight it.
There are a lot of times the corporation is unequivocally in the wrong, but they already billed your card and you have to fight to get it back. Being able to cancel the card first and force the corporation to take you to court and prove their case could help put the consumer on a more level playing field.
