Not anyone who needs to edit images in a professional sense. They arrive, try GIMP because they’re told it’s a Photoshop alternative then leave when they see the lack of normal features.
It’s actually even bad for students because to create with GIMP you have to do early 90s image editing workflows which are no longer used in real jobs.
A lot of people including me from time to time do need to deal with some image editing at work and do not need Photoshop (nor have I ever used Photoshop) and GIMP's powerful tools more than fill this need.
If anything, GIMP has brought more people to Linux from the dark side.
