I don't know if I agree. Its plausible, but also these businesses are monopolies, so even if they churn out shit it doesn't undermine their market position.
But I think Electron in particular is a symptom of the fact that GUI frameworks are in general horrible. There was a market gap for usability because using everything else was obtuse, and now we're paying for it.
Which businesses are monopolies? Slack surely isn't. If there's a market for faster chat clients because that's what people want then looks like a business opportunity?
FWIW all of slack competitors are also electron (rocket.chat et all), so it seems like you possibly know something that other engineers don't and might have a competitive advantage!
If someone released a GPU-accelerated version of Electron that had the performance of the GUI in basically every video game, it would destroy Electron. Now, would it be popular? I'm not sure, but let's say the answer is no. Ok, now imagine Google released that.
