lol that sucks for the company but that’s what you get when you don’t use some kind of MDM scheme to retain control over assets. It’s especially costly to learn this lesson with Macs though.
I repair and resell scrap computers and if you’re able to prove ownership or have a business that repairs or otherwise handles Mac computers the people at the Apple Store will disable the lock for you. They take down your name and tax id and stuff though, so there’s some accountability, and it’s not easy to get to that point when you look like a greaseball and aren’t a member of apples authorized repair program. Ask me how I know lol.
Tbh it’s no different than a Chromebook or windows laptop that shows the owners email based username (in the case of windows computers with Microsoft ids it shows the users real name as well!) at the login screen, except that you can’t wipe it and resell it.
