PBS was supposed to be a politically neutral venue to make educational lectures and artistic productions widely available to people who otherwise would never be able to see them.  But for a long time now PBS has strayed far from that benevolent mission.  PBS (and NPR) has become a leftwing propaganda medium.  Therefore it's quite proper for conservatives to launch a political attack on it and to cut its budget.   Big Bird is looking more like a turkey every day, and might get served up on someone's dinner plate.
