I don't understand this. They're very, very clearly marketing the Macbook Pro to developers. Read their press release, they have a section devoted to Unity performance for goodness sake.

Look at the older 2012-2015 models - arguably the entry point for many modern developers, the devices that were so good and so reliable it cemented their love for the brand.

There's a difference between pivoting your target demographic, and just making a bad device and hoping professionals won't notice.
