It has all this support for native platforms yet it’s always a clunky memory hog
Maybe so but it has improved a lot over time. The app devs share some responsibility too so it’s not all on Electron.
zero effort to respect the design language of the OS it’s running on.
That’s the Dev’s design choice, not a limitation of Electron.
I’m on macOS, I want the app to be a native macOS app. If I wanted it to look like a webpage, or Windows, or Linux GTK then I’d switch to one of those and expect it to match those paradigms.
I don’t disagree but at the end of the day it doesn’t matter to enough people for it to become an issue. People are used to Slack and the way it works.
Moreover the cost of building the same app 2x or 3x simply doesn’t make business sense.
