The company went insolvent and ceased trading in 2006. Later, David Schlesinger, directory of Open Source technologies at ACCESS, Inc., which had meanwhile become the owner of the BeOS source code, stated that there had never been a license agreement covering yellowTAB's use of the source code and that ZETA was therefore an infringed copy.2
