Update 3 May 2020: YouTube has meanwhile removed the two doctors’ “presser”. YouTube also sometimes deletes videos and channels when it shouldn’t. This time, I am very pleased that it did.
To my dismay, I had also received these doctors’ rubbish as news in an email a few days after I posted the stuff below. (If you subscribe to news media other people follow, people whose views may not overlap with your own, you get a much better idea of what is out there, what people outside of your own circles are thinking.) So I emailed them.
