I agree with you, I don't like it either, but the nicknames themselves are at least not made-up or "celebrity-inspired" names like the article was talking about. I'd rather be Eleanor, Eve or Katherine on the dotted line, but I'd take Ellie, Evie or Katie over Madison, Addison, Brianna, Savannah or Nevaeh, which all feature in the US top 50 for example (although I believe Madison's crept into our top 50 too). I suppose as a Brit, my tastes are broadly in line with the zeitgeist, that's all. Our charts aren't perfect :)
By the way, your squirrel signature made me laugh literally out loud, I didn't realise for a second that it wasn't part of the rest of the post so it briefly scrambled my brain!
