Hate to throw oil on an already blazing fire, but the probelm is more than clear just by the simple fact that they tell people to migrate to BitLocker, which is not open source and therefore certainly not secure (nothing Microsoft is, you can be damn' sure of that if you know legalese and read the transcripts of the Microsoft security hearings in the EU Parliament, and the existence of the NSA backdoors in Windows has been positively proven a long time ago).
Another point that I've already mentioned on the forum a long time ago, is that TrueCrypt was always a mess. That's partly why RealCrypt was preferred in linux and not TrueCrypt.
In fact, RealCrypt is not really used either, LUKS is used, but not with the standard encryption system, because that has been proven unsecure also.
It's an arms race, the world against the fascist US corporate elite and it's lapdog government.
In the mean time, things to avoid: UEFI systems, CA's (use DANE!), all Intel hardware and AMD hardware made in the New York fab, IBM hardware (China has unveiled probably security backdoors in IBM server hardware last week), MS-Windows (China has outlawed Windows for government use because of the backdoors, Germany has outlawed Windows for government use because the security "cannot be proven", but hasn't yet enforced the ban), any closed source software made by US companies, US phones with locked firmware, routers and telecom hardware by US companies, services on US servers, communications through US owned service providers, etc, etc.
For encryption of data, a good solution is to use Samsung SSD's bought outside of the US, and to use them with native hardware encryption coupled to fully flashed open source BIOS.
