This is why I personally am very reluctant to the sharing of well founded ideas on platforms such as github, in hackathons, in competitions, in recorded speeches etc. How unlikely it may seem, this is a great example that ideas with traction do get picked up and copied, and the originator screwed over. I honestly sometimes feel as if the openness is pushed and saluted, but with the ulterior motive to skim for ideas.
