If it doesn’t respect the Four Essential Freedoms of Free Gender it is not Free and Open Source Gender.

-The freedom to use the gender as you wish, for any purpose (freedom 0).

-The freedom to study how the gender works, and change it so it does behave as you wish (freedom 1). Access to the source code is a precondition for this.

-The freedom to redistribute copies so you can help others (freedom 2).

-The freedom to distribute copies of your modified versions to others (freedom 3). By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.
