"Repeating what other say" would be an opinion, but finding and bringing sources that expose factual scientific research is not.
Scientific research and sources:
US National Institutes of Health, studies and guidelines on COVID-19 treatment (https://www.covid19treatmentguidelines.nih.gov/therapies/antiviral-therapy/chloroquine-or-hydroxychloroquine-and-or-azithromycin/): The COVID-19 Treatment Guidelines Panel (the Panel) recommends against the use of chloroquine or hydroxychloroquine and/or azithromycin for the treatment of COVID-19 in hospitalized patients (AI) and in nonhospitalized patients (AIIa).
World Health Organization’s Guideline Development Group (https://apps.who.int/iris/bitstream/handle/10665/339877/WHO-2019-nCoV-prophylaxes-2021.1-eng.pdf#page=3): expert panel made a “strong recommendation” that hydroxychloroquine should not be used to prevent COVID-19 and said the drug has no meaningful effect on patients already infected.
The article is wrong as its results have been proven wrong by more recent studies.
Its content also goes against the latest medical recommendations, therefore spreading it without adding this crucial detail amounts to disinformation that can endanger lives, and should never be acceptable.
You still do not analyze the article and its information. You reply with guidelines made by groups of people who have made mistakes in the past. As I said, the article is criticizable. You can start by the design of the study (I am guiding you). If you read carefully my post, in the last paragraph (where I express my opinion), there is the word "may". I do not know your credentials, but your quotes do not help your points
