I've reverted the recent "official" and country of origin info in the infobox.  As mentioned above, BL was a "synthesis" of East & West, Hong Kong & Hollywood.  The BL Foundation is a California non-profit corp, so should California be the country of origin?  Moreover, the BLF is dedicated to BL as a whole, not just JKD.  So is the BLF the official organization which oversees JKD?  Not really.  This aspect of the article is subject to lots of POV, so ego stuff like "official" and "country of origin" is best left out, if only because we do not have WP:RS for it.
