you know your first two sentences aren't really honest. there's the secondary market, considering that apple keeps updating their devices past typical android equivalent you're getting same $/years of use value. there are SE models that are in line to cheaper android alternatives.
if you're poor you're probably not data hording TBs of data, because you've got other problems, so yes, this is all speaking from the point of the privilege, and you being here is also from the point of privilege.
and to answer your 3rd question -- i'll bite and say that this maybe true. but is it really apple's problem or the problem overall? where we're all mined for data and now when someone does offer security you scream that it's unfair. shouldn't you take the equivalent effort and write your legislator and ask them what they're doing about bringing the bar to the level that apple is bringing it to, for all of the poor people out there?
