Sometimes government export control regulations and trade sanctions can constrain your freedom to distribute copies of programs internationally. Software developers do not have the power to eliminate or override these restrictions, but what they can and must do is refuse to impose them as conditions of use of the program. In this way, the restrictions will not affect activities and people outside the jurisdictions of these governments. Thus, free software licenses must not require obedience to any nontrivial export regulations as a condition of exercising any of the essential freedoms.
Take Huckberry as an example. They team up with clothing retailers and sell exclusive versions of retailers' items on Huckberry's online store. For Huckberry, they are the single source where an interested shopper can purchase the made-for-Huckberry exclusive item. For the retailer, they get exposure to their brand while also having another online venue to find new customers. It's a win-win scenario that's a low-cost investment for the retailer.
Proprietary software on the other hand tends to use a different business model, where a customer of the proprietary application pays a fee for a license to legally access and use it. This license may grant the customer the ability to configure some or no parts of the software themselves. Often some level of support is included in the purchase of proprietary software, but additional support services (especially for enterprise applications) are usually available for an additional fee. Some proprietary software vendors will also customize software for a fee.
