The whole point of contracts and licenses is to explicitly spell out what is allowed and expected. I mean, who is to say "how much" support is expected if it's not written down. Matt wanted 8%. Why not 15%, or 1%?

The idea that users of open source software "owe" something back to the original developers is revisionist history, and if you don't like how users are using your software, why did you open source it with a permissive license in the first place? There are plenty more restrictive licenses (e.g. GPL) that support a more "if you take you have to give" model. Saying "well, we wanted to open source it but not that kind of open source" is BS.
