You are talking about people attempting to break the law...
"The first batch, published a week ago, included a conversation between Marek Belka, the chief of Poland's central bank, and Interior Minister Bartlomiej Sienkiewicz, in which they discussed how the central bank might use its power to help the government win reelection in 2015. Mr. Belka said that his condition for help would be "the dismissal of the finance minister" in favor of a “technical and apolitical” one. They also discussed the creation of a law that would allow the central bank to buy government debt on secondary markets, a practice known as quantitative easing.
Under Polish law, the central bank has to be independent from political interference. But Jacek Rostowski, the finance minister, did indeed lose his job in November last year and was replaced by Mateusz Szczurek, an economist with no political experience. And new laws that include a provision allowing quantitative easing are also now in the works."
Why yes, if you conspire to break the law and get recorded, this is a bad thing for you. I'm not sure why you cited one of the few cases such a recording would be perfectly acceptable.
That is actually the valid and good purpose of the media and the security apparatus. Exposing political corruption and bringing it to justice wherever possible.
