      @thegrugq @dguido @electrospaces I'm trying to reconcile the abs crap described in that article with the kind of rewrites @dguido suggests.

      @matthew_d_green @thegrugq @electrospaces you really think you can piece together the entire BB security story through public news articles?

      @matthew_d_green @thegrugq @electrospaces then maybe you shouldn't insinuate incompetence when you admittedly only know part of the story

          @dguido @thegrugq @electrospaces Because I was summarizing an article that described incompetence. Maybe I should have put a ? On it.
