I think the biggest complaint about electron is not bloat of shipping the app (a one time download, not a big deal in modern times), but running the app. Since each electron program uses its own instance of Chrome, there is no resource sharing and so memory consumption is high.
Absolutely. I don't really care about the size on disk, a little bit, but not really. What I really care about is some application using far too much RA - Chrome (and by extension Electron) is notourious.
