I would argue that in general, having a lower barrier of entry to software engineering is a good thing, especially for attracting people that might not have otherwise considered it.
Someone wants to build a 5 minute app for themselves and Electron happens to be the easiest way to do it? Go for it, there's nothing stopping them. If that app happens to be useful enough for others to use it, even better, that person just solved what could have potentially been a big deal for that user.
If the people using the app are content with the features/quality and the resources it uses, why does it matter so much, especially to a third party like armchair engineers on HN, if it was built natively, on Electron, or CrappierFrameworkThatWillEventuallyReplaceElectron?
If the app isn't usable by you (and this is a general you, not specifically directed at you), then the answer is simple: don't use it. Nobody is forcing you to use Electron or any app built with it if you don't want to.
If as a user your needs are not met, whether that's due to sluggishness from Electron, incompatibility from having a native-only solution, whathaveyou, then all you really have to do is wait. A competitor will come and take its place eventually; that's what the market is there for.
So far, it seems like VS Code is more than meeting its users' needs, but like I said above, other alternatives exist and will continue to exist, and they're all great if VS Code doesn't work for your particular use.
