FYI, WebKit itself takes hundred of engineers from Apple (which would be roughly similar to Blink). And this is only for the rendering engine, which is pretty small compared to the entire browser codebase. Thus Apple is investing a comparable amount of engineering resource into Safari. Where are "Other browsers"?
WebKit does not have hundreds of Apple assigned to it.

Not really.
Well, it's close to 100, according to https://news.ycombinator.com/item?id=22059393 ? You can bring up with other numbers to refute this.

Please don't assert this so lightly unless you have any evidence to support it. A rendering engine is just a tiny fraction and you gotta take care of literally thousands of other components to build a modern browser. This applies to Chrome, Firefox and even old good IE. I don't expect any valid reasons why the same logic cannot apply to Safari.
