> I’m saying I did not receive services as I thought promised. You made a tax-deductible donation to a nonprofit. What goods and services did Mozilla agree to deliver to you for that exactly? > I don’t need to prove a crime to force a chargeback. No, but you need a valid chargeback reason, or the bank will lose the dispute process. They might or might not cover that loss out of their own pocket if you're a valuable customer. > If I donate to a fraud, I’m allowed to charge it back. Fraud is a completely different chargeback reason than "goods or services not provided", with different standards of evidence, different default liability etc. > I’ve returned products by leaving them on the counter and issuing a chargeback. [...] And it’s not like the card issuer is going to pick the merchant in a dispute with a valued cardholder. And your issuing bank has almost certainly written off the loss (to make you happy and maintain your business), or potentially recouped it out of a separate product return insurance that's part of many credit cards. You're not sending the message you think you do with entitled/petty behavior like that, or at least not to the right recipient.
