But again, I would contest your claim that buymastercoin is associated with the mastercoin foundation; there is no link to buymastercoin.com on mastercoinfoundation.org, only mastercoin.org
EDIT: Or at least, I would need one of the board members to tell us that the foundation owns the domain name mastercoin.org
Ron Gross owns mastercoin.org.
