Why is this better than running Windows 98 on a guest VM (non-emulated) on modern x86 hardware?
Surely a modern hypervisor should be able to emulate a retro Voodoo 3D card.
Second sentence in the article:

Because that requires x86 hardware which some people no longer have.
No modern hypervisors emulate a Voodoo 3D card. The upcoming 86Box release will probably have Riva 128 and ATI Rage 128 emulation as well.
Using an accurate emulation of such a device means you can use the drivers that existed back then that games back then were QA'd on.
Most modern hypervisors aren't built with Windows 98 in mind, either - it's not really what they're for, and a modern Mac can't run an x86 hypervisor anyway.
