The pre-OSI people seem to be quite similar to the initial OSI board from that announcement
page you linked to. Looking at other board members who have served over the years, there is
even more overlap.
Other than becoming their own organisation (as opposed to being under the SPI umbrella), why
do you consider them to be two groups? There doesn't seem to be much evidence of a conspiracy
or a shadowy takeover. Whatever you think about the organisation, I don't think you can
accuse them of that.
