There are two separate issues here: Place-based names cause a stigma (an issue for new diseases, less so for historical ones) and that "Spanish flu" is actually completely wrong on the origins of that specific disease.
It was a global pandemic that didn't even start in Spain. We happen to be paying a lot of attention to it because it's the last really global pandemic of similar severity/spread to the COVID-19 outbreak. The increased attention to this little bit of history has us asking whether we should correct the inaccuracy in its name.
That isn't what I was asking. I asked, why now. What about this instance in time has prompted this? Also, I was talking about Wikipedia. Please do not move the goalposts on me.
I guess the Socratic method isn't going to work here.
Bluntly put, some folks are full Ministry-of-Truthing away at Wikipedia to help justify their attempts at erasure of the "Wuhan flu," China connection. That's why it is happening now. "See, we don't call it the 'Spanish flu,' so why should we call it ..."
Lyme disease was around in humans long before its identification in Old Lyme, CT, so it too is an inaccurate name.
