Why would they make a github repo with this exploit for a seemingly not-fixed bug? If you're a security researcher it shouldn't be that hard for you to replicate it, and if you're not, there's no reason for you to have access to an app that lets you easily MITM someone's tinder results.
It doesn't even have to be bad. I was very nearly kicked out of my middle school just for booting from (!) my own live Linux USB drive on a school computer.
I would say try VSCode with the Vim plugin. VSCode is much snappier than atom, the Vim plugin is quite good, the configuration files are easy to edit, built-in awesome git integration and project-wide search, and amazing plugin support.

It doesn't have to be easier, it has to be more approachable. The most important part of programming is problem solving no matter how you're doing it, visual, imperative, functional, etc. Some interfaces are much more friendly to different people than others. Text programming often puts off non-programmers instantly, and they are able to reason about visual programming languages much easier than they would text-based ones without putting more time into them.
