The article makes a strong case the Surgisphere is shady and the study is badly made but other than timing (paper published 22, ban started 25th) the article does not provide any further information that the Surgisphere study was the source of the WHO decision.
I quoted the unsupported accusation below.
Instead of performing its own due diligence, the WHO immediately relied on an observational study cloaked in the reputation of the nearly 200-year old medical journal The Lancet.
