The entire infantile humour / brogrammer / hipster / drama phenomenon. It started in Ruby (_why, Zed Shaw, GitHub, etc) then moved into JS as Node and CoffeeScript became popular with Rails users, now it's in Rust (again via Ruby).
I don't think it's always the same people or that it has anything to do with Ruby itself, it just seems like there's a certain culture that first grew in the Ruby / Rails community.
This post is the first infantile thing in this vein I can remember seeing related to Rust, and, as far as I know, the author has no connection to the Ruby community you describe, they're just choosing poor titles of their own accord (I agree with Steve that the title detracts).
