There is a trail of links from the article that will bring you to the download. Click on the author's name to see their profile, click on the project to see the project's profile, click on the link to the project website, then click on the link to the downloads page. While the trail is a bit much, it is important to keep in mind the article was an account of the author's experiences and it published on a portal for indie developers. A direct link may not have been seen as appropriate given the context.

While I agree with companies misrepresenting their products as open source as being a problem and believe the AGPL should have been mentioned, I do not see how the point about open source being hard to sell as being relevant. Not only are there are success stories in the world of open source, but the author made their success sound modest.
