There does seem to be some truth to what you're suggesting.
For whatever reason, there's a propensity for this sort of drama to occur within organizations and at events where Ruby and Ruby on Rails, or users of such technologies, are involved in some way.
Off hand, I can think of that controversial presentation at GoGaRuCo a few years ago, the controversy about the diversity of the presenters at the BritRuby conference a bit later, and this matter here. Then there was that whole "Donglegate" incident, which while it occurred at PyCon, it involved at least one person with some ties to the Ruby community. I'm sure there are other events I'm missing, too.
Maybe it's just the so-called "brogrammer" culture that's so ingrained within the Ruby world that's responsible. Regardless, for a community that's actually quite small, there seems to be a whole lot of this sort of strife.
