    Maybe they just don't like all these independant reentry estimates.
    In the case of UARS, they received quite some public FLAK for failing to provide 
    a final reentry position quickly. They might perceive these independant reentry 
    estimates as people "breathing down their neck".
    SSC providing us with orbital elements is a courtesy. They have no public duty 
    to do so.
