I’ve just tried it, and although the idea is interesting it doesn’t seem to be working as intended.
I’m pretty sure all of these are FOSS, and thy were tagged as proprietary:
- AnkiDroid
- Moonlight
- KDE Connect
- KeePassDX
- Lichess
- MPV
And these are also FOSS but were flagged as ‘Unknown’:
- MGit
- NetworkTools
- Simple Audio Converter
- Termux
- Yet Another Call Blocker
And there are others I’m not entirely sure if theyre FOSS or hybrid, that were also flagged as proprietary.
Also not a fan of needing to subscribe to give feedback (like pointing out FOSS alternatives or false positives).




Have you tried using JDownloader? Copy paste the URL to it, and see if it can scan and find the video. Not sure if that would work, but there’s a good chance.
If it doesn’t work, try yt-dlp.
