Another facet is that Jarosław Kaczyński pretends to be some kind of political hermit with no personal life caring only about the greater good. The song calls attention to his duplicity and double standards. What makes it especially dangerous - and what probably got it banned - is that Polish media are highly polarized and many people read only articles from one side. As a consequence, PiS supporters are highly unlikely to hear anything critical of the party. But a song spreads very differently and crosses borders. There was a similar situation where a documentary about pedophilia in Church was released. The ruling party and Church support each other. They didn't care the movie - which is freely available because it was crowdfunded - is available in the internet. But police cracked down on people who tried to show the film locally. Taking something like that "to the streets" would make it possible for PiS supporters - who are often less educated, older and internet-averse - to randomly run into the documentary movie.

Moral of the story: there's nothing spectacular about the song, it's even intentionally campy. The criticism is veiled and words polite. It was likely the fact that the message took the form of a song that made it intolerable. And the Trójka radio station folded not really because of a single song, rather it was the straw that broke the camel's back.
