I am beginning to believe that AWS has decided that Knox is a "hobby" much like Steve Jobs feels about the Apple TV. I purchased a license this past June - 5 months ago. In that time barely anything has been changed with Knox.
The UI still displays "10.5" and "10.4 or later" - Clearly 10.5 is "later" than 10.4 so that is just bizarre. Any mention of 10.6? 10.6 was released nearly 15 months ago. It's such a small fix (cosmetic) that it makes me think that the larger fixes are being completely ignored.
Also, when Knox was owned by it's original developers, the unmounted vault icon actually worked? When I initially downloaded Knox from AWS and this wasn't working, I thought "Well this must be some weird bug that they'll work out in the next few days." Nope. 5 Months later it still has the weird file type icon rather than the nice closed briefcase like it had even two years ago. I have attached an image showing the current icon (left) alongside the old icon (right) that I STILL USE from when I used Knox before it was purchased by AWS.
Why can't Knox create Sparsebundles!? It's a command line option? (-type UDIF|SPARSE|SPARSEBUNDLE) I don't want to use Knox back up. I want to use Time Machine. The core competency of Knox should be to create encrypted images and make them available in a simple way to normal users... not being a backup application.
From where I sit, it looks like AWS purchased Knox with the best intentions but have not invested the resources necessary to actually make it a prime time product. This would be fine if you didn't go to such an effort to market & sell paid licenses for it.
I was honestly hoping to be able to use Knox to help my entire family manage their data more securely but until AWS decides to give Knox the attention it needs, I will be unable to do so.
