I could see it's name as an impedance toward adoption in a corporate environment. The name "GIMP" certainly doesn't inspire confidence in someone who's never heard of it before. GLIMPSE, a fork of GIMP, certainly has a better name.
Companies adopted Git. They'll adopt Gimp if it's better than Photoshop.
On the other hand, in the US, "gimp" is always either an insult, a derogatory verb, or the open source project.
