Use of the definite article

Hello guys....yesterday I was leafing through a famous self study guide, and I came across these two sentences, which do not sound completely right to me: a) the famed assmil method keeps its finger on the pulse of media jargon; b) the opposition does not criticize government policies, it slams them. Personally, I would have written them as: c) the famed assmil method keeps its finger on the pulse of the jargon of the media; d) the opposition does not criticize the policies of the governement, it slams them. This is because I would use the definite article in front of "media" and "government". Moreover, I do not think that an extra article in front of "jargon" (likewise, I would say: the english language, the french language...) would be that bad. I am sure that both the sentences a) and b) are correct. I just have the feeling that they do not sound good to my brain, because I still cannot understand the flavour behind the use of the definite article in them.

Thank you very much in advance.
