voiding a waranty is one thing but intentionally destroying their property is another.
Huh?
Who intentionally destroyed someone's property?
If you're speaking of the phones that were "bricked" by an update, first think about how many Windows computers are rendered inoperable every Patch Tuesday by failed updates, or updates that broke other software. Do those folks sue Microsoft? (Answer: No.)
So, before you go around saying things like "intentionally", show me the figures for:
1. How many iPhones were bricked by the update, and
2. How many same-model iPhones were NOT bricked by the update.
Something was already wrong with the bricked phones prior to the update. Could have been a manufacturing defect, or something the user did, I dunno.
Got figures?
