I think there's just not really a way for high quality, user facing applications to be open source. And when you download free of charge proprietary apps, more often than not you're giving up your data/privacy as compensation. There are plenty of really great, free software applications: VLC, Handbrake, Audacity, etc. But most of the free software world is not end user applications. It's the OS, HTTP server, and other infrastructure software. The software that is open source is the software that big companies need, but it's not their main product. So they can justify paying employees to contribute to it, and get the patches upstreamed. I would definitely prefer my apps like Omnifocus or Overcast to open source. But even setting aside the financial viability, running an open source project opens you up to a million people flooding you with patch requests and flame wars. If you're developing a high quality app with opinionated UX and design, that's the last thing you want.
