Also, I remember having read about being internal opposition against the PC inside IBM ranks, as they made their mainframes were their bread and butter back then. Some inside IBM really wanted it to fail, hence some of the questionable engineering decisions on the PC design.

Tangential question: How do newest GPUs (without 2D guts at all?) like a $UNLIMITED_MONEY RTX3080Ti deal with DOS-era graphics?

It's still supported via the BIOS.

Every established computer company had a powerful minicomputer or mainframe division that hated PCs.
The IBM 5150 PC was actually intentionally developed on the other side of the continent from headquarters to insulate them from sabotage. The 5150 project had very little managerial oversight and a significant amount of freedom. *
It is part of why IBM suceeded in launching a useful personal computer where every other established player stumbled.

The PC AT, however, was deliberately crippled. It was underclocked to ensure it didn't offer minicomputer levels of performance.

*As an aside... one of the few rules they had to abide by was IBM's stringent component reliability standards. This prevented them from building a 68000-based system, as there simply weren't enough 68000s in the world to test them to IBM's standards when the processor decision was being made.

Not well, but they're still functional.
