FBI was investigating covid unemployment insurance fraud in Guam. I don't use Bitlocker, so I can't speak from experience; the articles say the default is keys backed up to MS servers in "the cloud", though users can choose to back up keys locally -- say, to a removable drive. As usual, most people stay with the default.
Camel's nose, thin end of the wedge, slippery slope, etc. As the Forbes article says, quoting Matt Green: “My experience is, once the U.S. government gets used to having a capability, it's very hard to get rid of it.”
