The Nano foundation got 7M/133M = 5% of the initial coins for a "developer found". Did they spend/distribute all of it or it is still saved?
Miners will get 2.4M/21.0M, that is a 11% inflation. And they have to spend most of it in the mining. Just call this 11% a developer found, and the difference is not so much.
