Payment service OpenAI only for those with a Mastercard but not for people with a Mastercard?

Am I the only one thinking its weird that the payment system only accepts Creditcards, while its not accepting all Mastercards.

Even if you have paypal it still demands a card. i give a Mastercard accepted every where in the world. This isnt considerd a accaptable card…

Sure but I have paypal and when I use the option paypal it still gets angry about the Acceptable card. A Creditcard isnt a standard card for stand people.

Every country uses different payment systems, cards etc. than if Open AI is so good and worldwide accepted, why dont they accept my legal payment method or cards?

Remove or change the option in paypal. no money no extra sure, but give the option to pay more than just a card only 20% of the world uses.. a mastercard is considerd a Creditcard than why isnt my mastercard considerd a creditcard?

sure there are debitcards, prepaid cards etc. but a creditcard is a mastercard. The problem is a credit card has a spending limit while my mastercard is directly connected to my bankaccount and has no limit… so why am I limited to use a worldwide accepted card for everything accept a payment for an openai supscription??? Like a creditcard is more expensive but limited.. while my mastercard can do everything the same way.

Is this just me??
