I have never heard of this Browser Choice Alliance. Let me tell you about my biggest annoyance with a monopolistic browser.
It’s Chrome on Android. If a web-app (PWA) is configured correctly with the appropriate manifest, Chrome allows you to “install” it on your device as if it was an app. This is called WebAPK.
You can’t do it with Firefox. You also can’t do it with Chromium-based browsers like Vivaldi, Brave, Opera, or whatever you like to use. You can only do it with Chrome.
This is where this feature is officially described, listing all the benefits it has over the simple shortcut option that other browsers can use: https://web.dev/articles/webapks
And notice the last question in the FAQ:
I am a developer of another browser on Android, can I have this seamless install process?
We are working on it. We are committed to making this available to all browsers on Android and we will have more details soon.
Last updated in 2017. Committed my ass.
Just shot an email about this over to this supposed alliance. It’s clearly led by Google so I expect my email to go directly to trash. But we’ll see.
They introduced so much friction that people at my workplace mostly gave up changing default browser from Edge to something else over and over. Most cited reason is „Edge is pretty much the same as Chrome, why resist”. Chrome engine monoculture is coming to bite Google in the ass.
