Sure, because apparently it's experimental. Owning an iPhone for 4 years, I bought an android device and the first thing I notice is that half the apps I use are very unstable. The quality of the software is way behind the iOS.
Kaepora is so full of himself, I'm not sure how anyone takes what he says or the apps he writes seriously. Glad that people are putting stock in more consistent developers these days (http://tobtu.com/decryptocat.php).
Well, in my opinion the real problem here is Apples lack of transparency. It's totally fine if they block an App, but at least they should be open about it and communicate to the world why/what the reasons are.
As we've seen in recent news events, when agencies/companies are not transparent, what happens is: corruption. Bad things happen when people are prevented from seeing what's going on behind the curtains.
