I don't disagree, but as someone who has written a bunch of personal tools (including a Tinder assistant lol) with electron and nwjs, think about why people are using these runtimes before you rip on it. Since so many people are doing it, there must be some good reasons.
Yes, they are using it because they are familiar with the web platform and want to go a step further. But that doesn't mean that all other ways to build programs for desktop use suck and we can only use a webkit engine. With stuff like electron, the result is bloated as hell and looks totally foreign.
EDIT: Just think of the major performance problems these electron based editors had and still have. Our compurters have become faster, so we just write more bloated and slower software?
