I think you might need to interpret "China" in the grandparent to this post as literally the land and people, instead of the more common meaning of the current government.
Taiwan's official view, as I understand it, is that they are the rightful government of the land and those people, and that the people currently reigning are illegitimate.
Look at the Straits Communiques to understand the KMT position. The DPP which won the election is far more likely to declare independence and ignore the history entirely.
Yes but the election prior to that argues against you as well. The reason for the most recent shift was because of Hong Kong protests and mainland action there. Prior to that there was a massive shift in favor of stronger relations with Mainland China.
It has never had a pro-PRC stance. That's a gross misrepresentation of the KMT view. At best, the KMT is a pro-status-quo party that simply thinks it's bad for business to start WW3 over the Chine issue.
Keep in mind there were 5 million votes for the opposition. Where does the leadership of TSMC fall under? We won’t know, are they more likely to support independence and change than young people in college? We can only make educated guesses.
The election doesn't tell you much. The young voters continue to prefer independence, while the shrinking older population prefers eventual unification with China. As more young people become eligible to vote, the independence crowd simply gets more votes.
KMT = economy party, they talk about "eventual reunification" in public statements to appease PRC so that cross-strait relations can remain good, which they think is crucial for the economy (since PRC is Taiwan's biggest trading partner). Pretty much nobody actually cares about reunification in and of itself, and KMT's current stance is that it won't happen until PRC becomes a democracy.
DPP = in addition to defying PRC's bullying about Taiwan government's statements regarding independence, DPP believes it is crucial to expand trade with other countries to reduce economic reliance on PRC.
So I would say there isn't really a huge generational divide regarding actually supporting re-unification, but certainly younger generation may not be as concerned about the potential economic ramifications of defying PRC.
It's not that the KMT wants to appease the PRC. Of course the KMT wishes for eventual reunification: they were kicked out of the rest of China by the communists but that does not mean that they should give up hope off regime change on the mainland.
