Its more about why would you go spend few months learning something, if you can build it in few days with electron.
An Electron app is not equal to a native app when it comes to UX and UI. Right off the bat: they require more resources to run, thus making your computer slower, a laptops battery last less on a single charge, and don't look and work like native apps thus requires the user to learn a new paradigm.
So instead of you, the developer, using a couple of months to learn a new paradigm, you put that burden on your users, and end up with something that is a whole lot worse than standard native apps on Mac, Linux and Windows.
If you only have 1 user, that is no hassle, but if you have 5 million users, that is a whole lot of time that a whole lot of users needs to spend collectively because you are lazy and want to ship something fast instead of shipping something great.
And no, I have never tried a great Electron app. I don't think they exist.
Exactly. That's the externality a lot of software companies nowadays generate.
The barrier to entry for Electron apps is 0, the same as for native apps.
But yet you used a either a browser or the HN mobile app (cordova) to post here... guess that means function > fitness.
You get the picture.
