re-signed by Wallgami's developer so macOS will run it inside a notarized app. Its source:

yt-dlp itself is released under the Unlicense. The executable bundles Python and other
components, some under the GNU GPL version 3, which makes the executable as a whole
GPLv3+. Every licence, and the maintainers' offer of source for the bundled components,
is in _internal/THIRD_PARTY_LICENSES.txt beside it. Wallgami runs yt-dlp as a separate
program, and updates it to newer official releases over time.
