After Prism would anyone trust icloud keychain?

First off - why would the NSA want your keychain?

Prism is all about getting the information directly from the service providers - no need to "steal" it using compromised user credentials.

What else would you put in this - a credit card number. Again - why would the NSA need to get your credit card number this way? Surely they can just ask the fucking bank directly and/or request info via FBI/CIA/etc. Credit Card companies already cover purchases from stolen cards/card numbers, so in the unlikely event some rogue NSA goon steals your CC number and buys a heap of tin foil hats, you're covered.

This of course all assumes that the NSA breaks the AES256 encryption on your keychain.

I really cannot understand the number of people going batshit crazy over a Crypto-Intel agency spying on people (shock fucking horror, what did you think they do all day?), but happily using search/email/document storage/etc from a for-profit company that freely states "we are going to scan all your email and track all the shit you do, so we can create a profile of your entire life, so we can target you with better ads"
