As a long-time Apollo user, this whole thing really bums me out. I was only a casual user until I started using Apollo, and the way that Christian would listen to the community and implement features and ideas was so refreshing.
Apollo made browsing an information-rich site like Reddit so much easier on mobile than on a desktop machine, and that's no small feat! It - and the wealth of great 3P apps - will be missed.
And all for what? Greed?
