A carpenter does woodworking for money. A woodworker does carpentry for fun. If you wanna charge for it, do it; if you don't want to, don't; it's up to you. And you can both give away your source code, and charge for it. Multiple/hybrid licensing, paid support, custom engineering, managed services, etc. This was an expected part of the free software movement when it started. I've always given away my code because I didn't write it to get paid, I wrote it because I just needed the code. It costs me nothing to give it away. I already benefit daily from other people doing this very thing, so it just makes sense to me to contribute back to the community I get so much from. The hobby software market was also like this when it first started (although unfortunately a lot of that was pirated software)
