OK. So if you meant theater, there were several issues about that. I remember at least two controversial theatre performances last year. One in Warsaw and one in Wroclaw. At least in the second case the problem was that this theater used to have "controvercial" performances. This theater is owned and somehow governed by voivodeship government. And voivodeship authorities are nominated by Poland government (in contrast to city autorities which are elected locally). So after previous election in Poland government was changed to much more conservative one. Then it changed voivodeship authorities to the one from the same political option. And voivodeship authorities replaced theater director to some conservative. This new director was conflicted with staff because all staff and previous director was liberal. And in fact some of performances were "to liberal" for this new director. And some of them was simply canceled.
In the second case the the theater is owned by capital city authorities which are more liberal than government so there is a lot of controvercial performances, that for example insults Catholics. In general in Poland there is a low that forbids insulting any religion, but in most cases it is used only when Catholic religion is insulted. So there was some big affair because radical Catholics feelt offended by this performence and there were several court cases about that but I don;t know the results.
As you can see there are some political pressures (or financial pressures) on theaters. The main difference between situation in Poland and in several other country is that here those who are conservatives try to forbid liberal performances and in USA for example conservatives performances are being forbidden or protested by liberals very often.

But it's not like we have a law that forbids any theatre performances.
