You are saving your own time and resources, in exchange for those of every one of your users. That insanely selfish attitude is why we are so incensed by this crap --- especially when it's developers making the lives of other developers worse.
Have some respect for your users; they might be developers too.
You're presuming that these users would have a product, even if it took several times longer for the developers to build. That isn't always (or maybe even often) true.
There are tradeoffs to be made; being absolutist about it isn't helpful.
> I think there's already more than enough quantity
That's just not true though. People need so much software, I've written more than one mediocre electron app for niche use cases that saved users multiple hours a week of mind-numbing work. That software that they're so happy to have in their lives would still not exist if it weren't for electron.
Almost none of those users are willing to pay 4x the price for native iOS, Android, Windows, Macos, and Linux apps (on top of the web version).
Also, I do not, in fact, have 4x the time to implement all that, vacation or not, nor do I have enough revenue to justify hiring a team of specialized developers.
It's about as selfish of me to be building on Electron as it is of you to not be working full time on Tauri or some other secure and high performance solution to this problem. Which is - not at all. Nobody is entitled to our dev time for free or against our will.
Realistically, the alternative to an Electron app is not native apps for multiple platforms. It is either a web app or a native app for a single platform.
