It was a FAQ once.

"VAX/VMS" was renamed "VAX VMS" and then was renamed OpenVMS when the
Alpha version came out and it wasn't a VAX-specific product any more.

_Ostensibly_ the reason was that this release had POSIX API
compliance, and a bunch of POSIX tools, optionally available free of
charge -- I think that before that, this cost extra.

Really, I cynically suspect it's because just the 3 letters wasn't
enough to trademark. After all VAX is probably better known as a brand
of vacuum cleaner, outside of old-timer IT circles.
