By that definition, nearly all seed from commercial packets is Open Pollinated. Ever see the seed production fields in Lompoc, CA? ( I think they belong to Burpee, but I could be wrong about that.) Really beautiful, huge blocks of color.
I do believe that most people agree with the Wikipedia definition of Open Pollinated:
" Open pollination is pollination by insects, birds, wind, or other natural mechanisms, and contrasts with cleistogamy, closed pollination, which is one of the many types of self pollination.[1] Open pollination also contrasts with controlled pollination, which is controlled so that all seeds of a crop are descended from parents with known traits, and are therefore more likely to have the desired traits.
The seeds of open-pollinated plants will produce new generations of those plants; however, because breeding is uncontrolled and the pollen (male parent) source is unknown, open pollination may result in plants that vary widely in genetic traits."
