Why was BritRuby cancelled?

Why do we always see this kind of drama coming out of the Ruby community?

It's like there's usually some sort of drama going on about some smart-ass comment that Zed or DHH or one of their other "rockstars" made somewhere. If it isn't that, then it's some uproar about some misogynist remark, action or presentation that some Rubyist was involved with. Now it's this "racism" nonsense.

I just can't remember this happening in any other programming- or software-related community. Sure, there will be debates and arguments at times, but at least there's some technological basis to them. This frequent Ruby drama often has absolutely nothing to do with technology.
