Add up all the time and resources wasted by an Electron application for all users over the lifetime of the application, then compare that to the amount of developer time supposedly saved.
This is why I hate this industry.
And it's not just about money. With Discord as an example, they are able to quickly develop and deliver a great product, iterate on new features and integrations, and support all major platforms including web browsers. Their choice to use a web based stack helps A LOT with this.
