Personally - I collect quite a few for different things. I almost always have at least chrome, firefox, ungoogled-chromium, and - recently - ladybird installed.
Not to mention a couple different chromium versions for various electron apps (slack, discord, etcher, bitwarden, vscode, postman, etc).
Different browsers do different things well, and electron does the "desktop app" niche better than the others right now. In the same way that ladybird does the "not tracked by corporations" part, and firefox does the "still supports manifest v2 extensions" part.
You can complain all you'd like (and I recognize you from other places hating on electron) and it's fine, but it doesn't change incentive structures for the folks deploying these, and as a full time linux user... I am SO fucking happy to have all the BS apps my company requires "just work" on my computers because of electron.
If you don't want to use software developed with Electron... more power to ya. Go make that choice. Leave the rest of us out of it.
From my side... it'd be great if we can make electron suck less (and trust me, I definitely agree that we can), but right now... it's still a pretty huge win.
Everything else, if there is a Web app, then I use the browser, no need to ship it alongside every single application out there.
It is like those garbage mobile apps, that are exactly the same website that I can access via the Webbrowser, packaged inside a "native" app.
And I say this as someone that works primarly in distributed systems and Web.
