Not only has it already been done, but it happened for most android phones pretty much the model year or two after apple did it. Enough time to get all their snarky ads in, let apple take the heat, and adjust their plans to follow the business model exactly - push people away from included headphones and towards their own +$100 Bluetooth headphones.
And the thing is, I love Bluetooth headphones. I used to love wired but the convenience is just too hard to beat. But everyone is price gouging the shit out of them compared to what it costs to produce. Granted I run mine very hard at probably an average of 10-12 hours a day split between two pairs at work and home, and I got around 10,000 hours out of my AirPods 2 before they died so I definitely got my moneys worth. But I refuse to pay $100 when I can get a knock-off pair for $4 that sound 95% as good with surprisingly similar battery life.
50 years ago during the Cold War the economic trajectory of the two wasn’t so different, and pakistan also included what would become Bangladesh. Nixon was opening relations with China after the sino Soviet split, and India probably wouldn’t agree to ally with someone who was in the process of economically integrating with a country that they were actively fighting a border war with (sino Indian border war 1962-present). Pre Iranian revolution Iran was also a major ally and shares a significant land border with Pakistan, and probably most importantly, Pakistan was an ideal country to serve as a funnel for military assistance to the mujahideen to help fight the Soviet Union in Afghanistan, which would arguably lead to the economic drain and political quagmire that was a primary factor in its collapse.
Of course the mujahideen would then evolve to become Al Qaeda which Pakistan would harbor, Iran would have its revolution, Bangladesh would gain independence, and the Pakistani military dictatorship would squander the potential of their country on a nuclear program and trying to maintain an army of equal strength to a country 10x their population. But the choice had a lot more geopolitical merit way back then, and once it had been made it is not so easy as forgive and forget or to counter the logistical inertia just because the circumstances change.
