Earlier quoted context omitted.
That's a little misrepresenting history... Taiwan was part of the Qing Empire and Japan took it in 1895 following China's defeat in the first Sino-Japanese War. China got it back after WWII.
Sure, and before the Qing armies invaded it was declared an independent kingdom by a Ming loyalist who was born in Japan to a Japanese mother, and before that there were a couple of European outposts and scattered settlers from Fujian, and before that there were indigenous peoples who themselves are part of an ethnic group that can now be found everywhere from Madagascar to New Zealand.

This is broadly true, not just "CCP framing". Obviously because of history and external influence there is also an "independentist" faction.
I don't see why this should be hard to accept unless the aim is indeed a "reframing" to push the independentist narrative, which does not really need it as the status quo mean de facto independence. So perhaps the aim is actually more along the lines of an anti-China narrative.
