Earlier quoted context omitted.
That Twillio doesn't protect you is bad. However, would a court agree you don't owe them the money? This recommendation seems like abuse of disputing a charge and will just get you banned from Twillio.
The court doesn't have to agree, only the card provider does. The customer has the right to dispute credit card charges thanks to the agreements between customer and card provider and between card provider and merchant. Twilio will get in trouble with Visa/Mastercard if customers say Twilio is dropping them for disputes the card provider finds in the customers' favor. This is why you always pay for sketchy merchants…
If it's a sufficiently large amount, Twilio will collect the money from you via other channels. Them losing a credit card dispute does not release you from liability.
>Twilio will get in trouble with Visa/Mastercard if customers say Twilio is dropping them for disputes the card provider finds in the customers' favor.
This is simply not true. Chargeback blacklists are standard and not prohibited by merchant agreements.
