The OP is right, it is no longer a true talent finding contest, although, it is inevitable that talent will come out of the show because of the sheer number of entrants to the show.
$imon Cowell made me realise that XF is only concerned with headlines a few years back when he didn't send Jedward home, despite having the casting vote that would have seen them gone, this after berating them for being a joke act for weeks.
Cowell changed the rules & if the show churns out a joke act winner as a result, then so be it.
