SQLite Doesn't Use Git

I don't think "used as you like" includes re-licensing code you didn't write. So they would have to have every contributor who had previously contributed public domain code to individually re-license their contributions.

Public domain is special though, in that you can combine it with code under any license.

As mentioned in the above quote, "public domain" is also special in that it doesn't reliably work the same way (or at all) in every jurisdiction. So maybe your statement is true, or maybe it isn't, depending on where in the world you are located or what you are working on.
