PR Web Worthless?

I've tried helping a to get traffic and rankings using PR Web a few times over the years, and found that it is mostly a racket. They charge $200+ for you to submit a press release that they say will be circulated to the press, and appear on important news sites, etc. Maybe so, but the value is so low. Let's take a look at an article I submitted in 2012 on PR Web:
Directory Script phpLD now on over 100,000 Websites
So it was released in April of 2010, and now let's look at how valuable it is now. Let's see who picked it up and still has it on their site"

1. The pagerank of the page on PR Web is 0.
2. Some sites like this one took the text, deleted the links in the article and don't even bother linking to phplinkdirectory.com. Wow, big thanks for that (not!) 
3. Then there is the so called Information Engineer that at least kept the links in the article intact. 
4. Then some site called True Predictions at least has a link at the bottom of the article but removed the links inside the article.

And  here is the real kicker! We have received a total of 17 referrals from PR Web since 2010!
