Yeah I’m pretty sure PC standing for Personal Computer was at one point a trademark of IBM. The IBM 5150 PC launched into a world full of different and incompatible microcomputers, even those that shared processors weren’t software compatible with each other. Hell, one of the things that sank Commodore was nearly none of their own machines were compatible with each other; most code written for a VIC20 wouldn’t run on a C64, etc.
It was IBM designing a machine from off the shelf components, buying an OS from Microsoft, and relying only on the copyright on the BIOS to keep the machine proprietary that led to their ubiquity even 40 years later. Compaq wrote a non-infringing BIOS and was able to put to market a machine compatible with the PC’s software library. And now, for the first time in microcomputer history, you had a de facto industry standard. Build an 8086 machine with ISA slots, write or license a BIOS that MS-DOS can talk to, and now you too can run that growing software library.
This was not a decision anyone made. The 8086 was quite literally slapped together because the engineers didn’t think it was going to be much of a big deal, IBM didn’t set out to create a standard that would stand for decades after they gave up all involvement with it. The modern x86 PC was metastasized as much as it was designed.
