Earlier quoted context omitted.
One of the two doesn't come with Google analytics automatically included and enabled by default to track your editor usage. I'll let you wonder which of the two.
I have searched for "ga.js" & "analytics" in the Ligttable repository, nothing came up. So I assume you mean it's Atom that comes with GA tracking enabled by default.
Why does Atom send usage data to Google Analytics?
In the same way that aggregate usage information is important when developing a web application, we've found that it's just as important for desktop applications, especially during the beta program. By knowing which Atom features are being used the most, and how the editor is performing, we can focus our development efforts in the right place.
