The link you sent just shows that they have zero days on Android: but they also have similar exploits available on iPhones.
Besides, the NSA having zero day vulnerabilities is nothing new and not limited to Android. Saying they have "remote sudo access" is misleading also and implies that they were deliberately built into android, although that may not be what you meant. Either way, the NSA will always have the type of people employed who can find zero days on smartphones and most importantly, not tell anyone about them.
Imagine if one of the thousands of hackers who attempt to jailbreak the iphone had those kinds of skills huh?
Also if you reside in one of the countries within the 14 eyes, they do have access to your phone[0]. It's a really good reason to think twice about buying american products and visiting their country knowing that they are creating a surveillance state. Wouldn't you agree?
