So if an individual unpaid volunteer spends their time doing a 2nd implementation, <bigco> might consider it for their browser. But they won't pay for a 2nd implementation with their own staff, even if they own a humongous chunk of the browser market (which comes with responsibilities) and even if it is a better algorithm. Sounds about right.
