Yes the report on Dexamethasone (DXM) sounds good, but it's from the same team that put out a dodgy negative report on HCQ just before touting DXM. Doesn't prove it's no good, but the politics flying around HCQ has been diabolical. Worth noting that DXM is claiming only a 30% success rate, and only for extreme cases (no effect in less extreme cases), so it's last-ditch not panacea.
HCQ, by contrast, has some impressive evidence, both clinical and other, eg.
1. Interesting studyin Italy - 65,000 people taking HCQ, only 20 cases of Covid-19, nodeaths or critical cases:
