I should be given the choice to turn it on though. I understand Apple not wanting to deal with the annoying customer who forgets their password, loses everything, and blames Apple. I’ve seen enough forgotten password people while waiting at the Genius Bar to sympathize with Apple. But just because some of their customers can’t handle the responsibility doesn’t mean none of their customers should have the option. I encrypt my hard drive despite Apple’s warnings about FireVault. I understand the risk, have weighed the pros and cons, and have taken steps to mitigate the risk.
It is very typical of Apple, unfortunately, to leave out power features in order to focus on excelling at the basics. I switched to an iPhone from a rooted Android a few years ago, and while I do miss that level of control, I don't have to worry about the overhead that that type of Android device commands.
