Was Neowin forced to delete article about WP8.1 security hole?

Today, I found the following article in my RSS reader:

When opening the URL, it only shows: "The article you were looking for could not be found".

Thanks to Google Cache, we are still able to read the shocking article.

I suspect Microsoft of forcing them to delete the article, since it mentions a heavy security issue with the ALL apps written for the winRT runtime in C#.

What do you think? Is it a good idea for Microsoft to apply a "security by applying a gag order"-policy?
