It's also a really well written paper. Isn't it impressive how people just read into it and assume that there must be all these criteria that make the data better without them being detailed or a control group? Not many academic papers can communicate things (of differing levels of veracity) that they want to communicate but can't say explicitly so well.
There seem to be a huge number of people reading about this topic online who just want to be comforted and are willing to throw all critical thinking out the window to that end. That's the only way I can figure why all these optimistic but poorly designed papers are being cheered on places like HN and /r/covid19, not to mention the news.
Theres a reason even the language of scams - snake oil - has an origin in health panacea. Health and money have ways of getting people to believe things that they should be quite a bit more sceptical of.
