This is very much like saying “Use Windows once, and Linux is ruined forever”.
Once I actually learned how to use GIMP, I was able to appreciate it. It does things differently than PhotoShop, and, in some cases, I preferred the GIMP way of doing things to PhotoShop. It does take time to learn, though, and you can’t just learn PS and then hop onto GIMP and expect to do things the same way.
