What they’re saying is: “we haven’t called out any specific games, but we told steam if they can’t prove a game is “lawful” well cut them off”.
That interpretation is inviable because Mastercard is claiming to allow "all" lawful purchases on its network. And, given a purchase is lawful unless proved contrariwise (as a consequence of innocence unless proved guilt), it would need evidence that a purchase is unlawful, in order to prevent it.
So it's more than just dictating what can be sold without actually stating it - people there are lying.
Now the real issue is that at the end of the Mastercard is in a position where this matters and they can influence things. Should work just like cash and leave the government to decide what items are legal/illegal.
Full agree.
Double reply regarding Stripe's open statement, as it's related to this topic:
Stripe is claiming to be "pressured" by an unknown party. But it's going out of its way to defend that party, by not naming it and by claiming it's a "partner".
