Facebook moved away from cross platform web based frameworks for its apps years ago.
Microsoft’s mobile and desktop apps (besides Teams which also sucks and VSCode which is pretty good) are not using web frameworks.
And most apps that would be suitable for PWAs are in fact free. How would Apple or Google benefit financially?
Besides most of the App Stores’s revenue comes from games
What happens when either Apple or Google introduce a new feature to their native platform?
I would definitely not use the ElectronJS Slack app if I had a choice.
People prefer Electron because it gives them a consistent environment across operating systems, OS versions/update patch numbers, browser versions etc.
If you write your app to work in all possible combinations of the above - like you'd write a web page - you can use OS web view.
But not everybody wants to do that because it's not as straight forward as just writing your app and being able to fully rely on your environment. Perhaps you actually need features that aren't universally available in the OS web view yet, and performance degradation because of polyfills is not acceptable.
Also, OS web view is usually locked down more than Electron. It's basically a browser without the UI around it. Then you need to hack your own native bridge instead of just using whatever Electron made. I guarantee your version is going to be worse, you simply don't have the combined resources of the Electron open source project.
People don’t prefer an application that takes up more memory, drains battery life and that’s not consistent with their other apps. Developers may prefer it.
How many users are switching back and forth between Windows and Macs?
The same applies in the other direction. When I was a Windows user, I hated the iTunes interface because it felt like a bad Mac port. I was a former Mac (and current) Mac user so I could tell.
Even before that, the Windows QuickTime Player felt like a bad port.
Software development is not just about the users. Many Electron apps are single dev ventures. It's not easy to maintain multiple different platform specific apps even for a large enterprise. The larger the app the more difficult it becomes.
And this says a lot about why people prefer commercial alternatives.
Except for all those popular Electron apps with lock-in effects, like Discord and Slack.
There are no alternatives to the Slack ElectronJS Desktop app. That's the whole point: they don't want to maintain native apps. And they don't open their API to let others do it, I guess because that may hurt their lock-in benefits.
A couple of years ago I worked on an app that ran on 5 platforms (iOS, Android, Windows, macOS, ChromeOS). Initially we used Phonegap and Electron but then we created our own native wrapper that used the OS webview.
Our macOS app went from 100MB to 5MB of download size and the memory usage also went down considerably. IIRC correctly it consumed like 15MB of memory.
It certainly didn't look native but for our use case (education) that was not an issue. We were able to target 5 platforms with a very small team and the GUI was a single codebase made with InfernoJS and MobX.
