I’m not worried about getting raided by the KGB or anything like that, but break-ins happen and my computer equipment would be a prime target for theft.
I occasionally cycle my backup drives off-site, so I want those encrypted as well.
The cost of encryption is very close to zero, so I don’t even entertain the question of whether I should encrypt or not. I just encrypt by default.
This is network-specific. It’s been going on for a few months at least. yt-dlp itself still works without sign-in, if your network is not “suspicious”.
Always worth making sure you’re updated to the latest version of yt-dlp, but this is probably a network thing.
