WebObjects was from NeXT. The Xserve saw regular updates until 2010. Mac OS Server was a GUI for a bunch of open source tools, and where it wasn’t (Workgroup Manager), they replaced with the MDM.

Apple had more money when they killed these than they did when these products were introduced. It’s not a resources issue. It’s a care issue. Same reason they fired the Mac OS Automation team. Same reason their documentation sucks hot diarrhea and all their good stuff is in the “documentation archive”. Penny pinching. “Shareholder value”. New blood destroying shit they didn’t understand.
