I can only disagree with guru because he clearly sees this as an offensive or dishonest action. You underestimate the “enemy” (surveillance). Honest people always make this mistake. You can see it throughout the history of mankind, in politics, everywhere.
We won’t drop the weapons when we have to deal with such organizations (sic). In Greece (I bet everywhere else) they call you for anything, banks, products, whatever they found out by surveillance that you might be interested in. If starting the call you say “our conversation will be recorded” they always hang up immediately.
The ability to do that is a weapon not to be thrown away. Use you honesty to use it properly. Knifes are used to cut bread. We will not throw them away because they can also kill.
