> Open Source Definition explicitly excludes [public domain]

Mis-information. The Open Source Definition (https://opensource.org/osd) has no such exclusion. Read it for yourself.

Sorry, I indeed should have said "deliberately" or "intentionally" instead of "explicitly". What I meant was that it's not included, and that not including it was a conscious choice rather than an oversight:

My reading is the core problem is that not every jurisdiction recognizes public domain dedications, so for some people, such software may be no different than "all rights reserved".
