I completely understand where your coming from. However, I think it's worth stressing that - from what I've seen - there are two major concerns. 1) Ambiguity.

I completely understand where your coming from. However, I think it's worth stressing that - from what I've seen - there are two major concerns. 1) Ambiguity. A lot of people aren't so much concerned over the license restrictions you have placed on the project, as completely confused over what those restrictions are. The GPL is written in a way which is extremely ambiguous for a JS framework and (partly) as a a result it is a vanishingly rare license in the web framework/JS space. You should spell out your understanding of what the license does and does not allow on your website. 1b) Your second option ("just send us an email") is also full of ambiguity. For good or ill, people in western cultures tend to hate this sort of haggling. A price sheet would be good, or at LEAST some clarification of the type of commercial license you imagine. Are you expecting to charge a flat rate per developer? Per website? Per visitor? Are you looking for revenue sharing deals? If I want to use Meteor for a closed-source app am I looking at the price of a cup of coffee? The price of a steak dinner? The price of a new smartphone? The price of a new car? Also, what protection do I have from you deciding to slash your commercial license costs by 80% after you think over the response you've been getting? 2) I think a lot of the concern is coming not so much from people who want to write closed source commercial apps as from people concerned that the restrictive license will hamper uptake. Everyone wants to get in on the ground floor of the next Rails/Django/Backbone, and to be able to brag in job interviews looking for an expert Meteor dev "sure, I've been using it since version 0.3!" But dual-licensed projects (like ExtJS) tend to have relatively low adoption. If nobody used Meteor, then Meteor's future isn't going to be as bright, and I'm less excited about using it myself. If everyone is using Meteor, then Meteor's future is bright, and it would behove me to learn it ASAP.
