I think you are fighting the wrong battle here kgun, the post is a genuine reference to this article. And you have caught the wrong fish in your net . But the question about whether targeting typo can be penalised or not is still valid though.

In regards to using typos for SEO, I believe it is a genuine method which has nothing to do with so-called "black hat" techniques. You are simply helping Google driving people to the right content, even if they have misspelled their search query.

And if you are using Google adwords for instance, the suggestion tool will provide you with misspelled keywords as recommendations. Since Google implicitly recommends to target misspelled keywords in your CPC campaigns, I don't see why they would prevent webmasters doing exactly the same thing in natural search listing.
