Should Sublime Text goes open source to save itself from falling?

- no heavy updates, ST3 is stuck in beta version for nearly 3 years or more.. - numerous free and light editors (VS Code, Atom) are gaining ground. (light i.e not heavy full IDE such as VS, Eclipse, Netbeans)

I'm a little bit concerned about its future and fearing, as well, its fall. (Talking about Atom, I still remember how nobody had believed in Google Chrome when it's launched and now it's ranked #1).
