-## Noncommercial Purposes
+## Noncompete
 
-Any noncommercial purpose is a permitted purpose.
+Any purpose is a permitted purpose, except for providing any
+product that competes with the software or any product the
+licensor or any of its affiliates provides using the software.
 
-## Personal Uses
+## Competition
 
-Personal use for research, experiment, and testing for
-the benefit of public knowledge, personal study, private
-entertainment, hobby projects, amateur pursuits, or religious
-observance, without any anticipated commercial application,
-is use for a permitted purpose.
+Goods and services compete even when they provide functionality
+through different kinds of interfaces or for different technical
+platforms.  Applications can compete with services, libraries
+with plugins, frameworks with development tools, and so on,
+even if they're written in different programming languages
+or for different computer architectures.  Goods and services
+compete even when provided free of charge.  If you market a
+product as a practical substitute for the software or another
+product, it definitely competes.

+the software or another product using the software, you may
+continue using versions of the software available under these
+terms beforehand to provide your competing product, but not
+any later versions.

+## Discontinued Products

+You may begin using the software to compete with a product
+or service that the licensor or any of its affiliates has
+stopped providing, unless the licensor includes a plain-text
+line beginning with `Licensor Line of Business:` with the
+software that mentions that line of business.
