This. It is exactly the problem with incentives.

At some point I was wondering why Tor was not offering incentives, which is something Nym was talking about. And I found an explanation on the Tor website that said something along those lines: "we thought about incentives, but we decided that we wanted contributions from people who cared, not from interested people". Makes sense to me.
