It just happened, probably too early to come to any conclusions.
I think the concern is that Wahl seems to have been a generally healthy person (although recently been feeling sick, according to https://news.ycombinator.com/item?id=33931689), wrote a critical article about a famously hard government, received a bunch of death threats and the day after drops dead. Again, too early to reach any conclusions, I guess we'll have to wait for a proper autopsy before reading too much into it.
