Translation:Certainly the big newspapers do not write it.
Yeah, the use of the present tense in Duolingo often seems "off". The sentence is perfectly grammatical, but without the context, it sounds strange. I often think it would be better if they just stuck with the present continuous form, rather than the simple present. "are not writing it" makes the sentence less of a general statement, while also making it more generally applicable.
Also, I forget, is there a different way to say "write about <something>"?
