> But why is my business software doing the same?

Shopify runs a payment network called Shop Pay, and that network has relationships with the credit card companies like Visa. Honestly how do you expect to transact in goods that almost nobody will do business in? Even if you have the listing, what supported Shopify payment system will do the business?

Yes I know about Shop Pay (it’s a wrapper around Stripe). And just like Stripe and PayPal, Shop Pay gives Shopify the right to stop users from selling certain products.

I’m talking about connecting Shopify to authorize.net (credit card gateway) and a custom high risk processor. In that case, we are not using Shop Pay. But Shopify can still unpublish and restrict what you sell. That’s the issue. No one is saying Shopify has to allow sellers to sell high risk items under Shop Pay. It’s when you connect to a different payment processor.
