People say this vulnerability was "not super large easy to exploit" because of one poorly-informed skeptical blog post that hit the top of HN, but the evidence strongly suggests that post was simply wrong, and we're just going to have to live with the misinformation until it decays.
At this point the play is simply to move the goalposts, suggesting that vulnerabilities don't matter so long as you yourself couldn't easily exploit them, regardless of what well-armed attackers can do with them. That's, obviously, not how software security works.
Are there better sources for understanding the scope of impact enabled by PHP2Shell? My impression from a variety of sources is that very few incidents can be clearly attributed to that vulnerability. As opposed the many other ol’ ways PHP applications get exploited.

What sort of evidence? What "strongly suggests" this was actually easy to exploit?
