@sysrq It's very difficult to validly place something into the public domain and in many countries doing so is not permitted.

The only license I've found that has a good chance of doing so properly is still in the drafting stage and is the WPDD: https://wpdd.info/


With the GPLv3+, you can defend freedom with your copyright, so you should jump at the chance to make the proprietary masters seethe rather than make them content.
