Who couldn't see this coming from a mile away?
Two things from this situation stand out to me. 1. How is this a security feature if it doesn't trigger without an update? If someone was to do something sinister and steal all the information on the phone, there's not a helluva lot of security to be gotten from Error-53. The guy from the original story had his phone fixed and working for months before he was prompted for a security update. If someone stole his info, Error-53 would have been no help whatsoever.
Imo, the fearmongering stolen data scenario is a false flag. If data is going to be stolen, it will be gone before the update.
2. MR is seriously downplaying the fact that Error-53 happens without unauthorized repairs. One line in the entire article: "Damaged phones also have the potential to give the error." Seemed like an afterthought.
Your first point is a good one.... and a point that i hadn't seen brought up before. As for your second... well... there are many types of damage that cause a phone to stop working properly or altogether. If someone damages the phone to the extent that it damages the connection between sensor and processor... why be surprised if problems occur....
