Fix that, and then the American people might consider not using encryption anymore.
That ship has sailed, and is not coming back. When the American Government is indistinguishable from any other type of criminal, you are well advised to protect yourself from them all.
...but the "proprietary" argument doesn't hold any water....
"Proprietary" means:
1) Support can be pulled at any time for any reason, and there isn't a thing you can do about it. See Visual Basic (it's so bizarre that you argue against your point, but don't even realize it).
2) You are locked-in to the vendor's whims, and there isn't a thing you can do about it.
3) You are restricted to the vendor's supported platforms, and there isn't a thing you can do about it.
4) You have no idea what is going on under the hood, and there isn't a thing you can do about it (under threat of fine and/or imprisonment).
There are more, but I don't have time.
