Electron is a crutch. A crutch that people resort to because it's effectively impossible to write quick and dirty cross-platform desktop apps in anything else, but, worse still, a _debilitating_ crutch that, unless you know what you are doing (and I daresay that is something people should be looking into) delivers overly bloated, resource-guzzling apps that wreck usability, battery life and (most visibly) RAM in _any_ OS.
I don't have 16GB of RAM everywhere. Statistically, NOBODY does, in the sense that the average user (who is not, usually, a developer or a power user) is probably using a Windows PC with 4GB of RAM where a _single_ Electron app can take up over half of system resources.
And I find the initial premises laughable. Whenever I ran Slack on my 16GB MacBook Pro, battery life took a nosedive - visibly so. JavaFX apps like Nightcode are far more efficient (but I digress and am probably summoning a few trolls).
So no, I don't think Electron is defensible. It is _marginally_ defensible if you want to get an MVP out, or if your real desktop app is still in the works. Excusing it by saying it will cost you more to hire someone who knows how to do cross-platform development in something like Qt or Xamarin and deliver a more efficient, higher quality product is not an excuse, it's a cop-out.
