To the larger point, do you know if Rovio did support/pay Eric in any other way than that hoodie?
Angry Birds generated $500M [0], supposedly.
I would also not be surprised if the Rovio developers, designers, testers, etc. who worked on this game did not get a share of that $500M pie - I actually assume they didn't.
But still, you know. Dare I say it - what about "fairness"? :-)

I don't know enough to give an answer. But I also wonder if Unity, using Box2D to empower games generating billions, paid him anything.
Box2d is open source. For better or for worse, Rovio are entitled to use it.
I find it odd how we frame fairness in regards to open source software. He licensed his software as MIT. It says anyone can you use it without owing the author anything. So how is it unfair?
To be clear, I think that open source maintainers deserve much more, but I don't understand why we rarely inspect the licenses as the source of the problem.
