Crucial P1 NVME 1TB is around 100 Euros in my neck of the woods so charging twice that for an 512GB upgrade is bonkers in my book but clearly I'm not the intended customer base.

I guess for companies flush with cash where every employees salary is in the six figure ballpark, the price of Mac configs don't raise any eyebrows in the list of expenses but at least in all companies I've worked so far if I'd have suggested we buy Macs, the bean counters would have had a fit.
