Meh. Microsoft built a text editor with it and only because it was the simplest choice to have finally a os-independent editor (maybe now they would have go for .net core if they had a good cross-ui library). Facebook and Google had to use it because you are talking about framework for the web, and sadly our browsers support directly only javascript as scripting language... they have not chosen it, they were forced to use it.
