[Nomentatus]

IANAL. From your example.

"Researcher shall use the Database only for non-commercial research and educational purposes."

So they saw you coming. Your efforts of whatever kind can't end up in a commercial product by you. Could you put your weights into the public domain? (Meaning others could profit.) Maybe. Might be a court case, but I think they'd lose it.

A later clause allows for-profit companies to do non-profit related research, as I read it.
