Pre-trained models license clarification

The License section of the readme mentions:
"The training data containing the annotation (and the models trained with these data) are available for **non-commercial research purposes only**."

If an organization/activity does not fall under this definition, are there any model buying/licensing options available or can these models never be used in this context?

Could someone clarify how both **"non-commercial"** and **"research purpose"** are exactly defined?
Does it need to be both "non-commercial" AND "research purpose" or is it "non-commercial" OR "research purpose"?

Some additional questions that could help clarify the statement:
- Is a non-profit organization considered non-commercial?
- Can a commercial company use the models for internal research projects (non-commercial research project, but commercial company)?
- Does the "research purpose" mean that these models can never be used in a production environment, even if the purpose is non-commercial?
