The main thing that Electron does is solve most of the platform abstraction issues. The only contender that comes close to this is Qt.

However, if you want to hire Qt developers, that's a much smaller pool and then you also need to pay Qt license fees for each one.

If you want to develop truly native applications, now you need to maintain builds for Windows, Mac OS and perhaps even Linux. You need developers familiar with all of these native frameworks.

Optimizing for developers isn't necessarily worse for users, if they can get more done in less time, users benefit. It's just not so obvious. No user will ever complain about a product they aren't using because it won't ship until next year with half the features.
