Unlicense Yourself: Set Your Code Free
unlicense.org
unlicense.org
I don’t think the OP understands copyright law. They include a warranty disclaimer right after they say the work is not copyrightable and therefore not licensed. So which is it?
You can use the WTFPL if you want to thumb your nose at copyright for political reasons, but don't care if it actually is usable for people that need to care about copyright law.
I don't see what this unlicense does better except the cheeky name.

The author disclaims copyright to this source code. In place of a legal notice, here is a blessing:
May you do good and not evil.
May you find forgiveness for yourself and forgive others.
May you share freely, never taking more than you give.
If you want people to be able to conveniently and confidently use the software to in a maximally open way, then it should have a 0BSD/2BSD license as a backstop. You can always include a blessing on top.
WTFPL and unlicense work against being fully open, and i suspect it's a mix of tongue-in-cheek and guerilla anti-copyright (e.g. if you believe in copyright law you can't use this hahahah). Both being commendable, but you're gatekeeping what should be free too then and also creating practical problems for sane, regular people who just want to legally use your awesome thing.
But I respect that if you’re going to go the route of no copyright / no license, at least SQLite owns it.
