It turns out that most of the things that ADHD people use as coping strategies just to be functional, are actually things that most (non-ADHD) people can use to be more effective and productive in their lives and work.

So, no, not everyone can or should be diagnosed as ADHD. But the tools are (mostly) universally applicable. I don't see the downside in popularizing those. (Since you posted a top-level comment instead of a reply to someone claiming to have ADHD, I have to assume that's your complaint, at any rate.)
