What specific "lies" did Mozilla engage in?
>If I donate to a fraud, I’m allowed to charge it back.
If you donate to someone claiming to be the Red Cross, but isn't actually, you can probably charge back, because you were deceived amount who the money is going to. If you donated to the Red Cross, but are angry that they did/didn't help in Gaza, you'll have a hard time charging back, because there's no deception going on. This is especially true if they didn't make specific claims about how the money would be spent. Mozilla's donation page currently says:
"The Mozilla Foundation is building a movement to reclaim the internet. Together we can create a future where our privacy is protected, AI is trustworthy, and irresponsible tech companies are held accountable. But that's only possible if we do it together."
The wording here is so squishy so it gives Mozilla wide latitude to do whatever they want with the money. As long as they don't spend it all on hookers and blow, it'll be hard to argue even in regular court that deception took place.
Finally, even if you're in the right, deception has occurred, AND the "donation" defense doesn't hold, the credit card case worker doesn't have the time or expertise to adjudicate all of this. They'll hear "donation", "I authorized this charge", and deny the chargeback.
>If you bought it recently on a card and return the car I honestly don’t see why not. I’ve returned products by leaving them on the counter and issuing a chargeback. The clerks almost always couldn’t care less. And it’s not like the card issuer is going to pick the merchant in a dispute with a valued cardholder.
AFAIK chargebacks are basically adjudicated via arbitration by visa or an independent arbitrator, not by the banks themselves. It's certainly not some sort of kangaroo court where the customer is always right. The bank could choose to compensate you themselves if they think it's not worth the hassle, but in that case you're just trading goodwill from the bank for a short term moral high.
