1. If you run this scheme enough and your credit card company flags your account for excessive chargebacks, you could very well have that card shut down and take a credit hit along with it. 2. More and more companies implement against (effectively) data brokers who are going to tie your chargeback history into a risk score. This very product from Stripe is absolutely going to score risky behavior in part based on past chargeback history.
What's easier & takes less time now is not a guarantee on something being a net good decision, so other people should think twice before going with a scheme like this.
