Just think of it: You start your lib, it becomes fairly popular; you think wow this deserves its own domain. Now it's more like a chore than a pet project, plus no one donates to your awesome lib - yes you believe in OSS, but BigBuckCorp who is using your lib could at least chip in. It is all a drag now, so you decide to move on, you owe them nothing, and they are giving you nothing. So years later your credit card expires, and you have to update it to update the domain, and you will definitely do it if you come to it but not now. And it's gone. Screw this...
