But still a browser that was created by Google and was bundled with the OS until 12 months ago, never mind how long it takes OEMs to roll it out. Android <=4.3 accounts for 75% of Android users:

Just because Google decided not to support it any more doesn't mean they shouldn't. Pointing out Firefox and Opera is all very well, but this is the default browser on Android <=4.3, and very few users explore alternative browsers (Chrome being the exception, to a point).
It's also the browser engine used in embedded webviews, don't forget.
