I think it’s intentional, those encryption (at rest/transit) applications are outside of MS control and you can assume outside of potential backdoors by three letters agencies, bitlocker vs veracrypt? Of course bitlocker is favorable from their perspective.

I wouldn’t be surprised if NSA already had a list of these applications and the strategies on how to cripple them or worse, compromise them.

Or found they’ve been compromised by someone else? ;)
