I agree! Having more than one (or two, if we include WebKit - but Blink is a fork of it, so ...) relevant browser engines would be great. But as it stands right now, the fact that I can build apps that have all capabilities that the end user would expect (push notifications, background sync, "Add to homescreen", offline capabilities) in the most popular browser out there and the fact that the latter is FLOSS (Chromium - obviously Chrome is not) means that IMHO we are in a much better place than a few years ago when web dev meant JQuery and IE8 polyfills. And that shows - I can now use only a browser, independent of the host OS, to do all of my days work (using Theia/VSCode in the browser is a joy) and even entertainment (remember when a proprietary OS and a proprietary native app was required to stream video?) completely from a free/libre and open source software. If that means that I have to accept a libre browser monopoly for now than that's much better than having to accept a proprietary host OS IMHO.
