Linux has a great history of splitting hairs over philosophical purity and practical practices.

Honestly, a fork is a probably a perfect panacea. The project will become a pair; one procuring funding at the price of it's soul, the other persisting as perfect (and pitifully prehistoric, save the proactive pedestrian). For a period both will produce positive momentum, but the paid product will peak higher and sooner, and fall precipitously. After the pitiable putrid product performs as well as pious poop, the persistent one will proceed to provide.

Tl;dr: ppppppppppppppppppp
