Proprietary and Git don’t really go well together. Anyone can use Git and you certainly don’t have to use this or any additional software with it. I’ve never used Tower, as everything I’ve wanted to do in Git has been accomplishable via the command line.

The necessity of this article is debatable however. As with the majority (all?) of software products (excluding games), there’s often always that “this tool solves a problem we had ourselves” component. A somewhat shallow piece of content marketing is what this appears to be.
