The second comment is the important one, where they completely miss the point of ease of use. (The first comment is right, installing stuff on a corporate comptuer is tricky.)
So let's look at ease of use! You need to have a server and separately manage GPG keys. Looks like an archival blu-ray wins on that front. (And yes I see where it's a goal to make this easy to use for everyone, it's not there yet.)
So whether tabeth is wrong or right to think it's of limited use, they are not fundamentally missing the point.
