Why aren't permissions always granted?

If an app needs to declare the permissions it uses when you install it, and then you can choose whether or not to install it based on that, why would some permissions not be granted by the OS? If the user accepts those permissions, the OS wouldn't know any better. The best way to do this would probably be to add an option where the user needs to specifically decide to allow these high-security permissions, and then an extra warning before installing each app that uses any of these permissions.
 
I'm not sure I understand what you are saying, but AFAIK some permissions require superuser access, or rooting, to be granted. Those are the only permissions I know of that can be denied by the phone.

I still don't know why the carriers don't want us to have root access. IMHO, what I do on my phone is none of their business, even if they did subsidize the cost. Unless it uses their equipment (like calling, texting, and 3G/4G internet) it's nobody's business but my own, and they have no right to tell me what I can and can't do.

Its not the carriers. Even if you bought the phone SIM-free from carriers, warranty from manufacturers would be voided (which is why carriers dont want them, because if you brick your phone, they cant return it to manufacturers). I buy my phones direct from Samsung Concept Store (in my country (ess than 20% of the population actually gets their phones from carriers and instead from stores) and I was told this. Its simply due to the fact that with rooting, you can overclock the proc, do things with the OS and stuff that basically circumvents anything the manufacturer coded. Its just their way of saying, whatever happens to your phone after rooting, its your fault not ours, so why would we cover it with warranty?

I agree with what you say, but remember, carriers are in the business of money making. If you have root access, you could easily get rid of all the crap bloatware that they love to install on phones.

Like Chanchan said, a big worry is warranty coverage. Just look through any of the sub forums and you will come across tons of people who post "I just got rooted, I deleted this and now my phone is screwed, HELP!!"

Guess I have to play Devil's advocate on the matter.
 
Rooted phones can potentially be "misused" by malicious third-party applications. Permission controls could be useful to naive users as it gives them an opportunity to understand what an app intends to do on their phone. For e.g. a puzzle game that requires Location permission should raise doubts in the minds of users.
