For those doubters, my protector will not come off, with all my spudgers, credit cards, ifixit it cards, suction cups etc. I've removed about 10 of these in the past with absolutely zero problems. Heat is helping a little. Duct tape is a joke. This one is glued on due to age or something like that. I've been this for an hour and its not working. Opening my iMac was much easier. I'll be removing these preemptively in the future.
