Have you read the android security model? It's a multi party security model which considers apps and users as equals. It's a legitimate security model and just because it's not what you want doesn't mean it's wrong.is it user hostile? Maybe. But that is different than saying it offers no security. It's also not worth bickering about every small decision that is made in line with that security model. If you want a different one, push for it via alternative OS.
