This is Ste's comment on blog.psmxy.org,
[Nullriver created a situation (that they appear to not care about) where if they feature an app, that isn’t hosted by them, on Installer’s “Featured” page, and the user doesn’t have the necessary repository added, then the app cannot be downloaded. The only way it can be sure of working is if Nullriver hosts the app, since they are the only repository guaranteed to be there. So, the developer moved TTR to Nullriver. Nice way to effectively steal one of my more popular apps, Nullriver. How many more of my packages will you “feature/steal”?]
Is he being a little too paranoid?
