Taken somewhat out of context, but "for the benefit of everyone" is fitting.

And it's good news.

Down with proprietary buses.  MCA doesn't gain you much (if anything),
except a higher price and fewer compatible boards and software.  There
are some theoretical advantages, but they don't pan out, at least not
with the available hardware and software.

The old ISA bus is not a limiting factor in increased performance, yet.
