laowhy86, bitter expats doing China-bad for clicks is well trodden career pivot. You can see clearly in his youtube timeline when he transitioned from prosaic China musings to anti-CPC bashing after he left the country. His authority or lack of absolutely has to do with the fact that he's a youtube travel blogger and not subject matter expert - again of which there are many - who has not endorsed such theories. I'm not appealing to a singular authority, but a community of China watchers where conspiracy theories are dismissed as conspiracy theories. Unless your conspiracy is that they all got bought off - including anti-China institutions - and are collectively incompetent. Or alternatively, a youtuber is endorsing conspiracy for clicks. Which is more likely? Which is the kind of thing a stupid person would entertain?
Re: Taiwan, they released the alleged emails that they had information on H2H on Dec31st. Never mind there's no way they would be able to verify such information since they only had their first imported case on Jan21st. There's Taiwanese interviews in early Jan where their own CDC deputy director stated it was impossible to verify H2H until new cases happen after Jan14th. Their Dec31st email turned out to be the exact correspondence provided by Wuhan medical officials to the WHO and other medical community prior - they are treating novel corona patients in isolation wards which is standard practice. AKA it was nothing. Also elevating Taiwan was part of a coordinated US propaganda push to undermine the WHO including that interview (by HK news no less) that attempts to discredit the WHO via ambush questions that's outside of the organization's let alone a scientist's purview. Identifying propaganda and manufactured consent is media literacy 101. Believing your countries propaganda over a competing narrative is understandable, but believing a youtuber over general consensus of experts is less so. That's Alex Jones territory.
