This Dev Bootcamp phenomenon negatively affects Ruby and Ruby on Rails community disproportionately more than any other. I think pretty much all these training courses sell Ruby on Rails as the goto platform to learn. If this trend continues, Rails will be where PHP is now (no offence to smart people doing PHP, but you know what I mean).
Ruby/Ruby on Rails community isn't new to dealing with other people bad mouthing them. Remember Zed Shaw declaring "Rails Is A Ghetto" (http://harmful.cat-v.org/software/ruby/rails/is-a-ghetto) in 2007? Despite many haters, Rails penetrated through Java/.NET duopoly, and it has gained a lot of respect since then. All the bad mouthing didn't matter back then. Rails had so many talented people. Really smart people were coming from Java and .NET world into Rails and some of them were very passionate about making the technology better. This trends is on a notable decline now.
