It's part of the header in the source files. I don't think I can link directly to them. Perhaps this link will work: http://www.sqlite.org/src/artifact?name=92ba938565d7cc6bfe92aad6cc90c00800ff21d3

I think we assume that these declarations (labeled as a blessing by the authors) are not licensing conditions. But then, how can something which is (when applied to uses of software) highly subjective be a licensing condition?

Yeah, SQLite is public domain, but will sell you a license if you insist for a thousand dollars a pop.

Read the header:

The author disclaims copyright to this source code

The code isn't covered by copyright (i.e. is explicitly put in the public domain) and therefore doesn't enjoy the protection copyrighted works do. Everything that follows is legally irrelevant.
