I think this has long stopped being a design goal. The OS is not the primary platform any more which everything orients around, it's an access point to the web. Products are determining design language now.

People don't expect Google to look 'like Windows' just because they're on a Windows OS, they expect Google to look like Material apps across all platforms. There's not 'windows spotify' or 'android spotify' but they expect the app to look the feel the same everywhere, and in that way companies actually benefit from using Electron.

In my experience the people who decide these things talk about branding. Not user expectations. Phone, tablet, and desktop apps have different interfaces anyway. And few people use more than 1 desktop OS and 1 mobile OS

I think this argument used to make sense to me as well, but since most apps I interact with are web apps in browsers these days, most of my interactions aren't with native widgets anyway and I don't really care anymore.

Many of us have been bludgeoned by web apps to the point of not caring any more … most web apps are slow, twitchy interfaces that shift constantly and the industry loves it because it allows them to utilize the armies of (used to be cheap) web developers but at a heavy cost to the user experience

As someone who switches between three platforms, I like that Electron apps are consistent and in sync. Back in the day when I was using Skype, I could never get used to either.

I don't know what Slack or Teams would look like with native UI components, but I am pretty sure I would consider it inferior to what we have at the moment. The possibly improved performance and memory footprint would be nice but not enough for me to care about.
