The only thing that really bothers me personally about shorteners is not knowing where I'm going to end up, and not being able to identify articles I've read before. A shortener with a dedicated domain and user-chosen ids should cover that just fine. The only outstanding issue in the article is a single extra DNS lookup, which is pretty minor compared to the massive chains which were causing the problem.

There's an additional security issue when a URL shortener is abandoned and malware groups pick up the domain.

If the shortener is tied to a site than why is that risk any greater than the risk of the site itself being abandoned?
