The maintainer of this software is a bit nutty, but actually this is pretty timely and captures two important truths that a lot of people might not appreciate: 1. International payments are hard because every country has its own system, and the people there have their own payment methods. In the US, you take it for granted that anyone with money to spend has a credit card that can make payments in US Dollars. It isn't valid to assume that for users outside the US. People may not have credit cards at all, or if they do they can't necessarily (economically) pay in US Dollars as the currency. 2. There are a LOT of potential users in international markets. Focusing on the First World (US, Europe, Japan, etc.) might be a great way to keep your project simple or speed up your launch, but you're leaving literally billions of potential users on the table if you don't even try to consider India, China, etc.
