Open Sourcing Apps
Bit of a crazy idea.. Open Sourcing all your apps. Might seem like a bit of a wild idea but in my opinion, if your really behind Privacy and Security then FLOSS is the best way forward.
And from a business perspective, it's not like you'll have free loaders using the services as anyone who has tried VyprVPN for Mac knows, get Viscosity or what ever and you still need to authenticate with your username/password! If I used Boxcryptor with DumpTruck I'm sure that would work out the same.
At least Open Source Cyphr since it's free! It makes sense and if you look at your biggest competitor, Text Secure/Signal, it's Open Source and highly recommended not only because Moxie made it but because hackers, IT Sec guys and more can see the code!
