Even Microsoft with their unlimited money and resources couldn't afford to develop their own engine.

Mozilla survives by whatever money Google is giving them, laid off most of their staff and shut down development on engine improvements like Servo (whether you like it or not, Servo is dead).

That leaves WebKit as almost the only meaningful opposition in the face of Chrome's onslaught. And it's going to get worse.
