ffs she still writes her songs, she just shares writing and producing credits with whoever she brings into the studio.
imogen heap wrote an entire blog post about how she had fallen for the characterization of swift as a puppet, then was shocked that she walked into the studio with a complete song that just needed a collaboration on the music production (clean, from 1988).
there are clips online of her completing the writing as she is singing it in the studio and the people in the room are tweaking single words of HER writing with her, not handing her verses. bam- max martin collaboration.
stop sharing hearsay about people you don't know much about.
