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.
Maintainers who have such blatant disregard for users should not be rewarded or celebrated.
