Some of these contradictions are fractal - i.e. contradictions all the way down :) For example the independent Radio and TV isn't that independent actually but in practice is. Partially this is because of the insecurities of the times these institutions were setup in making people in power unsure about true independence - so they wanted a control mechanism. The end result is an institution that is deeply coupled into the government but that has at the same time to pretend to be independent to such a degree most people inside it just act that way and its output is sorta neutral except in very slight tonal shift ways and in some individual cases. instances that are very German-culturally local? This is very hard to explain correctly but easy to just explain it wrongly - Let me do that now and translate it to American.

Imagine an institution being dependent and biased in exactly the opposite way that fox news is independent and balanced. Imagine a government-independent institution where you join a controlling organ and after sworn in you are invited to 2 after-meetings at the same time. One invitation comes in a red letter the other in a blue letter. Yet everybody has to be independent because that is what it is supposed to be. Germans can be very very stubborn about that.

this is sorta incomplete and wrong but I think gets you the taste for the setup? If not complain in the replies :)
