PolyForm Project has launched the last of its first tranche of licenses: Perimeter and Defensive. Each of these licenses are used to make source code available, but place certain limitations on its use.
The Perimeter license prohibits use of the software in a manner competitive with the software. The Defensive license prohibits use in a manner competitive with the products and services of the company licensing the software.
This adds to the PloyForm suite of source-available licenses released last year. Below is a handy chart to show the differences among them.
