"I can't use this to make money". Sad face.

If I had a company, which is a for-profit entity, I wouldn't want competitors to use my company's tech for free either.

I wonder, let's say one uses it on an open source project that accepts donations. Is that non-commercial enough? Or is it a no-no because money is involved? I'm just curious.

I'm glad such free datasets exist even if they are restricted to educational/hobby use.
