The comment is badly phrased, but go and actually look into First Berlin. One of their offerings is exactly this sort of paid-for micro/small-cap research.
The phrasing itself might be ambiguous but the reality is not. NWBO paid for this. Go ask GZ or DI if you would like to settle this.
Relevant disclosure says First Berlin may have had investment banking, consulting, or paid research agreements with a covered company within the past 12 months
