Part of me is amazed that so many apps continue to rely exclusively on the Google Play Store for distribution and monetization. With Google's track record, it's practically negligent to build a business which is completely dependent on their proprietary services. That said, there's also probably no money in Android apps it isn't on the Google Play Store. I doubt most Android users know how to install apps from anywhere else, much less search other app catalogs. So I guess I really shouldn't be amazed at all.
