Activation Lock is in fact not a good software because Apple have the keys.

If they refuse to accept the responsibility that comes with owning the keys, which, basically comes down to helping the customer when they can authenticate him, they should not own the key at all. At least they could be honest when they say they can’t do anything.

Because, reading this post, my question is not "why Apple don’t help?" but rather "why did we give them our keys if they are not willing to use them to help us ?"

What is a more legitimate use case than OP simple case that justify Apple’s decision power over Activation Lock.
