I understand you might want to monetize WikiWand later on, but the source being available shouldn't hurt your ability to do so, and in fact using a popular code hosting provider such as github will likely even accelerate its improvement :)
Hi Waldir. We might release some parts of WikiWand (but not all of it) as Open Source. But this will be in the future.

Thanks for the answer. I'll be looking forward to such open-sourcing, and hopefully contribute something. :)
Just one thing: I don't think "completed" is the right label to apply to this suggestion. "Under review" or "Planned" would convey the current status more accurately and actually match your response. Don't you agree?
