Mine is newer than that exploit so no. But also a flaw in the implementation doesn't invalidate the reason for implementing it in the first place. Anti theft features on android and ios have likely saved hundreds of thousands of phones from being stolen, if not millions.

But how often does a server gets stolen from a data center?

It surely makes sense for phones as it makes less profitable to steal them (as you could only sell parts of the phone and even that can be blocked). Maybe even for laptops but not for desktops and servers.

They’re not worried about stolen servers, they’re worried about flashing malware to the motherboard (possibly without physical intervention)

At least one attack they're trying to mitigate is firmware attacks on systems being shipped to the data center.
