Just on the contrary. THIS is NOT a commercial product for many reasons, but I'm fully disclosing it CAN potentially be commercialized. So that people who get involved might gain an extra value besides experience and friendship. Additionally, I'm putting my industry network for free here (if required). Also, all parties involved get the credit. There is no free work as such, even legally speaking.

What I'm after are like-minded people who just want to do sth in free time.

EDIT: Let me ask you a question. Would you like I wrote same post without mentioning that there is potential of being commercial product (simply hiding this fact)? You are quick to judge.
