I agree it quite outrageous all the RAM & Size on disk & CPU an electron app requires. But on the other hand what are the other alternative for a one codebase multiplatform app? If the program fulfills their needs well enough, users don't care what it's written in or how fat it is. And multi-platform matters. I've seen blog posts on how to get Sketch running on Windows using a Mac VM. Talk about using system resources.
