Did you rule out the obvious explanation, i.e., that this Mac had a
previous owner, and the previous owner invoked Find My Mac at some point?
As to a culprit, I would look to the reseller from whom you bought this
machine and not Apple itself.  Was Apple even involved directly in this
transaction, other than the original sale of the new MBP to its first owner?

 Here's me, having to deal with a 48 channel live recording over the
 course of six shows. Since my MADI gear is kinda heavy and the rental
 company had a Dante system on offer, I dusted off the 2013 Macbook pro I
 bought used, purchased a Dante virtual soundcard license from Audinate
 and happily tracked the first three shows with Ardour.
 On the train on an off-day, I started a rough mix-down so that the
 client can begin the selection process. In the middle of exporting, my
 Mac shuts down and boots into a PIN unlock screen, telling me it has
 been locked via "Find-my-Mac".
 For the record, this Macbook had been purchased from a reputable large
 online dealer, and it had been factory-reset and completely installed
 from scratch.
 The first thing I find as I frantically research this issue (on my
 proper laptop, that is controlled by me, not by some iFuckwits), is that
 this iFeature even contains the option of a remote data wipe.
 My excuses to my fellow passengers who got in the way of a stream of
 expletives suddenly bursting forth from an otherwise unobtrusive
 business traveller, as said traveller notices he doesn't have a
 screwdriver to yank his data drive out of this ransomware machine, and
 cannot even be sure it's off when it says it's off because of course the
 battery cannot be removed without major surgery, either.
 Was able to salvage the data at home using a real operating system on
 real hardware, and today I'm going to find an authorized mac reseller
 and give the guy at the guru bar a day he will remember and testify
 about at the next Apple employee incentive day.
 Long story short: don't.

 Holy...
 Glad you got your data at least. This would also freak me out a lot...
