The premise of the article is ridiculous. Sure, Apple has built a great brand that they can leverage into huge sales for the iPad Mini. I have no doubt it will be the most successful tablet in its size class within a few months. But to pretend that this means the Mini's development wasn't driven by the existing competitors is just silly. Apple jumped into this market because everyone else proved it out first.
Edit: And this is to say nothing of profits.
TLDR: There in Russia we don't have "I am Mac vs I am PC" advertisements.
It's not explicitly mentioning the Nexus 7, but this is at the top of the iPad Mini's 'design' page on Apple.com: http://i.imgur.com/7Mg92.png

I wrote this in a previous post: The iPad Mini is different than anything Apple has done before. For the first time Apple is NOT building a product to enchant brand new customers and grow their brand. Instead they are filling a hole that they feel was threatening to pull their customers into other ecosystems. "Don't mind those other, more affordable playgrounds. Pay attention to how we mill the shit out of this block of aluminum just for you."
What I mean is that most of Apple's actions seem to fall in line with what the article is suggesting. The one exception to this is, as you stated, the press conference. The press conference was designed around and addressed the exact questions that the press asks.
Now, what we don't see is Apple's website or TV spots filled with comparisons to the Nexus 7.
Why? Different target audiences.
Steve Jobs famously ridiculed the idea of smartphones before they released the iPhone.
