It's not even free software!

NASA Open Source Agreement license is not approved by the Free Software Foundation because its "original creation" clause bars derivatives combining third-party code.

The fact that this non-copyleft license is approved by the Open Source Initiative is as far as I know, the only thing that makes free software a proper subset of open source software.

Yeah, this is one of the very rare instances when the OSI and the FSF disagree on a license.

Thankfully, it looks like NASA has stopped using this weird license. The newer stuff that I see here seems to be under other more common free and open source licenses.

Why do you think they've stopped using NOSA? The page claims to show 253 projects and in the same time contains 239 occurrences of "NASA Open Source 3.0" which, for some reason, is the name of links to https://opensource.org/licenses/NASA-1.3
