Isn't the reason why many applications and libraries use Chromium due to Gecko's too Firefox-centric APIs?

I read a post here on HN a few months (years?) ago where a developer was really trying to use Gecko for their own application and got frustrated so much that they gave up and switched to Chromium.

Gecko is architected to be used as a framework, not a library, which means it tries to dictate a lot of aspects of how your code is supposed to be structured. Whereas Webkit/Blink is the other way around.

It predates KHTML/Webkit by several years so some additional legacy baggage is to be expected.

I've been led to believe that the APIs are mostly undocumented and often changing.
