Electron does not magically make your app work like shit - if you treat it like any other framework and actually invest resources into architecture and optimization it (surprise!) results in a good software, eg: vs code. Problem is it also allows to disregard all that and quickly prototype a solution that works good enough for some, and forget about all the optimization. That's real problem, but it's not tied in any way to electron. Same people would go and make a shitty app in qt if there was no electron, or just wouldn't make anything.
