It's bad to analyze this issue through the medium of a long-form article, which wraps the story up in emotional narrative. Here is a better write-up in the MIT Technology review:

The gist of the problem is this:
> The Amsterdam company spent more than $100 million testing the drug and carving a path through Europe’s medical rules and regulations, which weren’t geared to consider a new technology like gene therapy. Initially, for instance, regulators said they expected a clinical trial of 342 patients. Executives wryly noted that there were only 250 people with the disease in all of Europe.
> Nor has Glybera convinced the national regulators in Europe who decide what drugs get reimbursed. Last year, French authorities said they would not pay for the drug. Germany judged Glybera’s benefits “non-quantifiable.” It leaves doctors and insurers to make decisions on a case-by-case basis.
Here's a drug that cost $100 million to make, and will require even more money to move through clinical trials in the U.S. And the pool of potential patients is a less than 1,000 people, and oh many of then can't pay either because they lack insurance (U.S.) or the cost/benefit panel math doesn't work out (Europe).
Viewing this after-the-fact leads one astray, into thinking there is some problem with the system that leaves this potential cure out of the hands of patients. Patents, money, it's all just a proxy for effort in, benefit out. Even if you had the government make this drug, you're talking huge amounts of money per patient, which few governments would pony up. (And rightfully so, because you could save a lot more lives with that amount of tax dollars.) The answer is probably that this drug doesn't make economic sense, and the abandonment of it by the maker is just an indication that it was a misguided effort to begin with.
