Apple is pretty easy to get contacts and such out, contacts and such can all be exported as .vcs, and email stays with email accounts, the real bitch is iTunes because media purchased there stays there, non-transferable.Thanks for the ideas. If we ignore privacy for a moment, does Apple make it hard to get data out of their ecosystem? Like, what if all my contacts are in Apple and I decide later I don't want to use Apple's stuff anymore? How do I transfer my contacts elsewhere?
Is there possibly an assumption at play here? Namely that Apple will always demand certain legal requirements to be met? In principle, Apple could get cozier with law enforcement in the future. (I'm neither trying to imply they will or won't.)
Apple, and Microsoft are famous for making law enforcement jump through the whole dog and pony show, because if they don't they open themselves up to a lot of legal actions from a lot of different groups and if they can't prove that they followed the law in the country where the data was hosted then you better believe they are gonna loose that one and if they loose it for one person then everybody there can sue for a couple of reasons, no big payouts for anybody who isn't in the legal teams involved but its very bad president to set and a terrible business decision that the board gather the villagers for.
Could Apple get unnaturally cozy with law enforcement, sure, but your kids could also turn to the feds and snitch you out for the contents of that hidden folder in System32 you thought you hid. Anything is possible, just not likely.
