Since I was downvoted please allow me to explain by expanding on that question with more questions:

What sort of license did you have on Nodester's code prior to acquisition?

You said "We also used the following open source libraries / NPM modules written by talented Node.JS / Javascript developers:"

For any open-source work you used, did you leave the original author's copyright or credit in the code?

Did you pay the original authors anything for their work?

What types of licenses were used in the code you forked?

At what point did you let everyone know you were closing the public repository and making it private so you could sell it?

I apologize if this sounds abrasive, but this smacks of getting people to work for free under the notion of a truly open-source project.
