Yeah, the security of their profit.

No, security on the fact that when thieves break into my office, they leave the Apple computers because they know they are just dead weight with zero resale value.

They grab all of the other hardware though, the ones with no protections.

I'm having a hard time believing that these measures are by any means preventing theft. The scene with a thief going "oh no, it's an Apple device! I am not gonna steal it" is almost comical.

Devices will be stolen anyway and scrapped/dropped instead.

PSA: Enable Bitlocker and LUKS on your devices, folks. Your device is 100% going to be targeted now.

I have second-hand knowledge of a situation where a friend's office was broken into, the thieves left all Apple computers but grabbed monitors and PCs.

The thieves weren't random crackheads breaking in on a whim though, they specifically knew what the expensive stuff looked like (colour calibrated displays, drawing tablets) and left the cheap and impossible to resell stuff alone.

And then you find the place the thief dropped it at, via Find My?
