You're mistaken in thinking that we're conflating sleep and hibernate
modes.
Microsoft's response of using two factor authentication is silly. It
doesn't actually stop our attacks. In certain circumstances, it may shorten the window of attack for a specific type of user but it's mostly irrelevant. Consider a mail server with an encrypted drive, no proximity sensor or two factor authentication is going to help you. A seizure will still result in someone getting the keys that are in memory - unless you're using some sort of secure crypto co-processor (which no one is).
From your own paper:
Microsoft ... recommends configuring BitLocker in "advanced mode," where it protects the disk key using the TPM along with a
password or a key on a removable
USB device. However, even with these measures, BitLocker is vulnerable
if an attacker gets to the system
while the screen is locked or the computer is asleep (though not if it
is hibernating or powered off). So in other words, hibernate does make a difference, especially if you follow their guidelines.
