Comment So Apple doesn't trust the end user (Score 1) 539
A company rarely researches something without a reason, so Apple has obviously seen enough loss from warranty replacement to try to find some way to shift the blame from themselves to the consumer for a product's failure. They have also apparently justified this by seeing a large percentage of these replacements being approved by inaccurate failure descriptions from users. If this is true, the new sensors would be a (somewhat) legitimate countermeasure.
Or Apple could just be looking for a way to shift the blame to the users by just stating, "You broke it, we have sensors that prove it," regardless of what really happened.
Either way, it amounts to declaring war on the end users on the warranty front.
