I used to be guilty of this with FormAPI [1]. I heard that it was a good idea to collect the credit card information in the sign up form, and then charge the card automatically after the 7-day free trial. But then people would just forget about it and I would basically be stealing their money for a few months until they cancelled. I had to refund a few people who were angry about it. I removed the credit card field from the sign-up form. I was also thinking that this might reduce friction, but I think it actually lowered my "conversion rate". (In quotes because it doesn't really count if you "convert" people who just forgot about it.) Another way would be to keep the credit input on the sign up form, but require an explicit opt-in before I start the subscription. I don't know that would help. If someone actually needs the service then they're going to add a credit card. FormAPI isn't a "nice-to-have" service, it either solves your problem or it doesn't.
