It already is, though granted the phrasing is usually, "It was sure nice of Xerox to provide all that free technology for Apple and Microsoft."
Only on HN is $1,000,000 in stock considered "free."
Also, it wasn’t as much tech (bitmapped displays and computer mice existed elsewhere) as a vision that Apple took from Xerox, and they improved upon it/changed it quite a bit. Examples:
- Alto’s GUI is verb-object, Mac is object-verb
- Alto doesn’t have overlapping windows.
- did Alto have cross-process copy-paste?
- simplifying the mouse down to a single button may have been necessary to gain acceptance. (For comparison, look at https://youtu.be/2Z43y94Dfzk?feature=shared)
