@aks I'm not a tyrant that enslaves people with a yoke of unjust power (proprietary software), so the software I release is always free and authorizes copying - unauthorized copying of my software is impossible as a result.

It seems that a lot of proprietary software is just a bunch of MIT expat and BSD 3-clause software copied and pasted, with the license terms somehow infringed (but nothing happens, as such copyright holders signal their intention to surrender by selecting such pushover licenses), plus minimal changes to achieve x thing, but of course those developers claim that such software is "theirs", even though they didn't write most of it.
