You have to use a permissive license, otherwise your software will be ignored by all distributions. Which means it won't be available even for non-profit users.

There should be a non-profit-software Linux distribution that is only for non-leeches. But as it is, the OSS landscape favors corporations.

I'm beginning to wonder how much that software-needs-to-be-free propaganda has been spread in the 90s and early 00s by the beneficiaries (corporations and foundations).
