Linus did make git literally for himself, and by extension the kernel community. If you look at his quote about the name "Git," I think it portrays accurately the wry attitude of mock-antagonism linus feels around git:
It's not negative at all. It is a credit to Linus as a creator. Linus made a great tool and the command line UI is enough for him. Gitbox just makes his creation accessible to others and everybody wins.
"Linus made Git for himself. Gitbox brings Git to everyone."
Without Linus' free creation this app wouldn't exist at all.
