Seeing as how 1. at least 4 collaborators of hers (that I know of) have said that 70% of the song was written by her (Ed Sheeran, Dan Wilson, Imogen Heap, John Paul White) and 2. her songwriting voice is clear in all of the songs an 3. none of her songs are written by anyone else, I wouldn't say that she doesn't write…

She might be known for it, but it's a completely false notion that she acts as the victim. Even in her earliest albums, she always looked at things from both sides of the story and/or had songs where she took the blame, etc. In fact, this is one of the things I really like about her. I wouldn't grudge any artist…
