But what if Apple delete function does not really deletes things you would need to run a better deleting application like you can on other OSs to be sure a delete is unrecoverable.

The point is about freedom to do what you want with your hardware, give the people a way to remove the restrictions, put a huge warning but let me do what I want with a physical object I own.

Gee, Mr. Sarcastic, aren't we now?

"Delete" has always been separate from "purge" since the beginning of PCs.
