Any and all of these possibilities (vulnerability, illegal, or both) must be legalized or otherwise reframed as a cost of doing business. Every human deserves to be informed, whoever they are, regardless of status, wherever they are in the world. That we've allowed blackbox proceedings to take over these small quadrants of human society is a societal failure. The burden to secure such systems shall always fall upon the makers of those systems.
Let me be very clear that any excuse made under the veil of security including the enshrining of such in our books of law is incompatible with a society that respects the dignity to live free. It is a vicious abuse of power by those with knowledge over those robbed of it.
