It might have something to do with both countries being founded and governed by Fascists. It bears remembering that the KMT colonized the island of Taiwan in much the same way that Israel colonized Palestine; with a swift and brutal round of ethnic cleansing to secure their local hegemony, followed by decades of military support from Fascists in the West.
I don’t think China should invade Taiwan but it drives me up the wall that so many people think that they are some plucky little democracy standing up to the big, bad, commies, when the reality is that they are just another hyper-capitalist settler-colonial project in the same vein as the US, Israel, Canada, etc.
I remember the internet before Google, and how game changing it was to have all of the internet indexed in one place (even if that wasn’t actually quite true back then). If you had asked me 15, 10, even 5 years ago if I would be cheering its downfall and yearning for a return to a simpler, far less centralized internet, I would have called you crazy. And yet here we are.
