As a developer perspective, it's a interesting topic. It's true that free choice should exist but it's true too that this kind of web browser market dominance is very delicate. Anyone remember what happened with Microsoft when they had the browser monopoly? Was a disaster, they used their dominance to engage developers to code only for IE by creating JavaScript APIs that only worked in IE. That's the reason because jQuery was born, to help developers write using a single codebase for IE and another browsers.
We don't want to repeat that story. Browser competition is so important but non-devs people don't understand by obvious reasons. I'm an open source contributor and I believe in free choice but in this case I'm on the Apple's side and I have another particular reason for this.
Google wants to add hardware capabilities to Chromium. They are advocating and proposing several APIs hardware-related like WebUSB, Web Bluetooth, WebSerial, etc. You can find more info in
https://web.dev/fugu-status/. I think this is not the nature of the web, I feel it like force the web to be something else, against it's principles and foundations along with possible security breaches in those APIs (

Apple has neglected the web for several years, happily they are working hard in the webkit team to take the engine to the next level. Just hope it's not too late.
