"But still... Business Insider: ok or iffy, in general".

It should be ok.Businesses Insider media bias

He's just saying that Business Insider was using the think-tank info, and provided a direct source, so you can check their info directly. Then again, many media outlets use and quote other sources. Nothing strange imo.

Also, basically the nuance some ppl are giving in the comments is that in the end of the day a think-tank is giving an analysis from their lazy confi chairs, and are not in the frontline, and for that matter any analysis is not necessarily" the truth". But this think tank is of good repute, imo.
