That's weird, I've had nothing but a great experience with the React Router team. Can you point to an example?

How is you using someone else's open source package "rewarding" them?

I think that when someone provides an open source project they are doing everyone a favour. We then have a choice not to use it. But using their free thing is certainly not doing them a favour unless we are somehow contributing back.

May I ask what are you making reference to? And do you happen to know a better library?
