In dem vs im

My question is why isn't this written

"Im Gedicht greift Böhmermann Erdogan an"

Answer

Using "in dem" instead of "im" puts some emphasis on "dem", meaning: In this specific poem, not any poem. It is a bit like using "diesem" instead of "dem", but not as strong.

Answer

It's like asking why people sometimes use I am instead of I'm. There's really no difference. In some cases it just sounds better.

Answer

In addition to Alexandre I would say that '' In dem' sounds more formal and is used more in written language. 'Im' is mostly used in spoken language.
