Hiring talent to build browsers is not as easy as throwing money.

The bottleneck is engineers who have the know how to build it.

Building your own browser could be a shitty business decision if you can't compete with Chrome for ad dollars.

A browser makes sense if you can bundle it with an OS.

Android : chrome, ios: safari and Windows: Edge

Facebook makes a shit ton of money from ads people click on chrome.

Alibaba already have their own browser of a sort (https://en.wikipedia.org/wiki/UC_Browser). As I understand it, it's some kind of thin mobile browser which renders on the server side.

There are multiple versions of UC browser. My understanding of it is:

- uc mobile on Android now uses the blink engine, it used to use Webkit. - uc mini ( I think that's the name) has server renderer but it's "uc engine" is a derivative of gecko (not checked recently)

Samsung actually has a browser: http://www.samsung.com/global/galaxy/apps/samsung-internet/

Quite similar to Chrome, but has support for ad blockers etc.

Amazon sort of has their own browser called Silk. It's based on Chromium so it's not a built from the ground up endeavor but has been customized on their Fire devices to 'enhance' the browsing experience in a way that seems to benefit Amazon.

Samsung makes their own browser on Android.

it uses webkit/blink underneath, so that doesn't really count.
