As others have said "non-commercial use only" means "not open source". But ignoring that for the moment, what does "non-commercial" even mean? Is the license violated if the software is used on a website that has ads? Can a for-profit company use it for any purpose? Can a self-employed consultant use it to assist with their work?
In academia there's a lot of "for research purposes only, get a license otherwise" software releases. Again, the line for what is allowed and what isn't is very vague.
