I don't know if anyone has already mentioned this, but the whole name change (from Taliban to Opposing Forces) actually makes the game more realistic. My brother-in-law, an Afghan War marine vet, says that they always called the guys they were fighting "Opposing Forces" because, and this is clearly reflected in the game, the Taliban itself is only one component of the confederated groups that are all having a being-bad-guys field day in Afghanistan at the moment.
The remnants of the Taliban are fighting against us, NATO and the Afghan Army with Al-Qaeda flunkies from a dozen countries, Chechen separatists / Islamists, Iranian "military advisers," local Afghani warlords who oppose the Taliban, the new Afghani government, and any other powers attempting to reduce their local control, and a whole host of other guys of various native and non-native ethnicities and sects trying to take advantage of a disrupted situation to further personal / ideological / political goals. Some of the same groups are also fighting in Iraq where they ally themselves with local anti-government / anti-American forces.
So by changing the name, EA is actually making the game more realistic. Am I the only one who's noted this?
