Polaroid has become nothing more than a brand name. There is nothing left of Polaroid film except for a refurbished machine the Impossible Project bought.
What the author is writing about is not using Polaroid as a good example, but as an example of what not to do. "Mistakes: It could be that the purpose of your life is only to serve as a warning to others."
Another one of the problems with the article is that the author doesn't have any understanding of what it takes to manufacture film. Kodak can't do a small run, so it can't sell to tiny niche markets, like a Kodachrome run or a Plus-X run. The author has some good points, but aside from indexing executive pay to company profits, Kodak is doing all that it can.
