Palestine occupies a special place in the oppression hierarchy. They are the most oppressed of all, their voices are therefore especially important, and it naturally follows that when they report the numbers of the dead, "their voices" cannot be ignored etc. No other prominent voices with access to Gaza exist to calculate civilian or militant deaths, anyway, so the media defaults to the numbers they get from Hamas. It's a perfect informational and ideological monopoly on the storyline.
