Hans started moving to Taiwan in the 1600s, then you had that big influx as the Chinese Revolution wound down.

There's also Native Taiwanese - https://en.wikipedia.org/wiki/Austronesian_peoples, they even make up about 2% of the population, I think they all want the Hans to pickup and leave their lands.

The native natives are more aligned with the KMT (ok, super aligned). The Hans before 1949 are mostly from Fujian, who are not known for being the most patriotic (and indeed, became dominant in overseas Chinese communities in SE Asia, NYC, and so on...). Post 1949 was the rich Chinese and KMT officials from everywhere escaping the communists, who also own much of the island's economy and want closer ties to China (so they can make more money).
