Advertising done the right way...
I can certify that AppsFire is engaging in the same business practices... they wanted to charge $5,000 for our App to even *appear* in their apps.
If you can read French, then I highly recommend that you read my interview here:

The ecosystem is filled with various value propositions at the end-user and at the business level. Not all fit in the same bag. It's not that simple.
Your comment above is a loaded gun, 3 times over: "certify", "same", "even". Together, and alone, these 3 words invalidate your statement. Please allow me to elaborate.
First and foremost, Appsfire is a pure algorithmic app discovery experience. No business transaction involved in the streams that we display in the main screen. A user may have many streams, based on interests, price sensitivity, etc... We float the very best apps based on a technology that we developed called the App Score, a note between 0 and 100 that tries to summarize the true value of an app (think of it as a rotten tomatoes or metascore for movies). We dig deep in the 800,000+ apps to show the most interesting ones, but the built-in search engine lets you search for any and ALL apps. So econgeek's app may very well appear if searched, and better yet, be shown in priority if it's any good.
How do we make a living? Well, we run advertising in our app! It's clearly marked and shows in two places: the splash page at launch, once a day, that shows the PROMOTED APP OF THE DAY (clearly marked as such), and then as a thin banner at the top of the main screen (again, clearly marked, and not part of the algorithmic recommendations). Yes, buying that spot is a commercial service, like buying a page in the New York Times!!! And it doesn't come cheap because we have a large audience (well, not like the NYTimes, but hey, it's cheaper than an ad in the NYTimes too!!!).
"same" business practices? Nope. Not same pricing model. Not same promises. Plain ol' advertising model, transparent, with proper attribution.
Convinced yet?
