"It's look more like unfinished action in present so why don't they use Present Perfect?"
It is talking about a presentation of the news of the week, available on their site.
Such things are presented to the visitor in an "on demand" fashion - only when the visitor clicks something, it starts.
So it is not an "unfinished" action because it doesn't even start until the user activates it.
Yes, the news content has already been produced, but the sentence is saying it "from the user's point of view".
For the user, the news is just waiting there to be activated, never been started before. It has no "past".
And when there is no past involved in any way, present perfect is totally out of the question.
