Shopify is looking to force more developers into their 20% cut to squeeze more revenue out of their existing partners since the business isn't growing fast enough on the seller side. On top of the obvious issues with the 20% cut, other platforms like BigCommerce have copied Shopify's model. So now I need to pay out 40% to support both? This falls apart quickly if you support more than 1 shopping cart platform.<p>I suspect that the major players negotiate exceptions. I don't for a second believe that the large companies you see on the Shopify App Store pay their 20% cut. They would never agree to that.<p>I do agree that this will lead to a regression and force app developers into using Private/Custom apps, making for a worse and less secure experience for Shopify customers.
