If you are worried about the Russians stealing your computer to decrypt the hard drive, you should be expected to have solid understanding of where all the potential decryption keys are kept.
I personally am happy for my Microsoft account to contain a copy. Yes it is an issue if I were to need security from a government, (either from subpoena or espionage). But it provides a very convenient backup of the recovery key, and security from random theft, which is my actual concern.
Also you can disable backing up the keys if you want to. People who need security from state level actors should be expected to take responsibility for proper configuration themselves.
