Software Exclusivity
====================

It's OK to make software for UNIX only.
If you're writing sane[0] software, than attempting to fit it into Windows (mostly), and Mac (maybe) is usually more effort than it's worth.

The main benefit of writing for UNIX is in the simplicity of POSIX; you only have to write the same software once.
The implicit benefit is not indirectly[1] supporting Winblows.

[0]: As in, small utilities designed to be used at maximum as part of a script.
[1]: Yes, WSL exists. But how many people will either; a. see the installation process and give up, b. use WSL, and then decide to move to UNIX proper.
