Add to this how fabricated the "wet-market" theory just feels. Perhaps it may be a viable theory, but it smells like such BS, the kind of bad-but-effective theory you know you could get away with thanks to classic "ooh weird foreigner food racism." No one's going to stop to ask, uh, why NOW?
Doesn't seem fabricated to me. Zoonotic disease transmission is the norm. Add population growth, rampant development encroaching on habitats, stresses and migrations due to climate disaster, and the "why now?" seems pretty obvious.
