There was the Wuhan ophthalmologist[1] who pulled the alarm but got a visit by police and eventually succumbed to the disease.
Of course it would have been great if the Chinese were more transparent during those early days (and in general honestly), but it's pretty clear that the original outbreak was just the first smoke escaping from inside the burning roof: by late December it was already an uncontained epidemic that had spread far outside Wuhan.
We'd like something that would pick up the disease before it makes it to the epidemic status.
The probability of death for a healthy 30-something year old is lower than their probability to die in a car crash (1/10 to 1/100 of all cause mortality for that age group).
It’s a game of probability, of course, but it turns out that whistle blowers often suffer from “coincidences” and “low probability events”, and whenever that happens, I try to take note.
Wuhan lost a significant number of medical professionals presumably due to this.
Think about this: If he hadn't died, he probably would have received much less attention.
There were a few other eloquent Chinese whistle-blowers from the early days, Jan-Feb 2020, who have been silenced by government threats or by being detained, who do not have the public recognition of Dr Li - probably because they didn't die.

The 0.02% number covers 20-49; It is lopsided, so it's likely that 30 is much less and 49 is much more ... ; So, it's not 1/100 or 1/1000 as I claimed, likely 1/10.
Your numbers are off by a factor of at least 50.
