I think that's a poor excuse for not having a linux version. By that logic, we wouldn't have sublime because vim/emacs should be enough.
As I see it, the main reason I like to use linux on my development boxes is flexibility(or call it freedom if you want, I don't like doing so). I can do things in whatever way works best for me and I can create scripts/install packages to glue stuff together fairly easily to adapt to my workflow.
That was rather my point. It's not that Linux doesn't need UIs because their users all use CLIs, it's that it's users all user CLIs because anyone who'd like a nice UI stays well away.
I never said anything about removing existing software (such as sublime). I was talking about there being less incentive to create a git gui for a user base that is - from my experience - happy with the current cli interface or any other already existing client (such as magit for emacs).
