Partly just open market, I believe. Someone had a patent on a design, so
someone else came up with a competing design. They used to be known by the
company that invented (eg Milton, Schrader, etc).
But there are some minor differences, for example with the "Tru-Flate" (aka
automotive) ones you have to pull back the collar to make a connection.
With the "industrial" ones, you can just force it together and it will push
the collar back.
My experience was that the industrial couplers would start leaking after a
few years of service (and these were supposedly quality couplers, not from
HF). So I switched to Tru-Flate and haven't had a problem since. YMMV
