This is clearly anecdotal, but nearly every dev/engineer from every company I have ever worked for has had an MBP as their work laptop.
I've seen them at University and some non STEM students homes.
That said, I see iPhones at work, but probably because they are not critical to doing anything other than email.
Software engineering is Engineering like sandwich Engineer is Engineering.
They should use "specialist". It's not like they are using science to prove something will work.
