I try to speak the gospel of backing up your bitlocker recovery key to anyone who will listen without their eyes glazing over.
You can turn it off, if you’re okay with going without encryption; if it’s a mobile computer, like a laptop or something, encryption is a good idea, so just back up the key in a safe place, even just emailing it to yourself and you’re all set.
The bullshit is that the bitlocker dialog won’t save a file that contains your recovery key, to the drive that’s encrypted; my recommendation is to “print” it to a PDF, which you can save anywhere you want. Once you have it, attach it to an email and send it to yourself, or toss it in your Google drive or whatever.
Full disk encryption is, IMO, a great thing to have, but to rugpull people by just enabling it and not giving them the information to secure access to their data, or even really inform them that it’s on, is complete fucking horse shit.
