Hey. HEY. Listen up, people doing hobby stuff.
If you share your work, it's okay to want to get paid for it.
Even if it's stuff you give away in other forms or to individuals. Even if it's built on the free work of others. As long as you're not violating a license somewhere, you do nothing wrong by charging to cover your costs working on things, or building things, or maintaining things, or creating things.
We all need to get by. Giving stuff away is great. It's not *required.*
