The Winnie the Pooh meme is such a mild jab (along the same lines as calling Trump a cheeto) that the creators disavow, I'm glad some Chinese netizens see it for what it is, regardless of the team's Sunflower Movement-like pro-independence stance (which is clearly there with their musical choices and the way Detention depicted the KMT). I'm not big on markets, though, and I'm not someone who would ever support attacking someone for "violating the precepts and customs of a market," unless it were a clear case of corruption like insider trading, money laundering, etc. If you come to Taiwan and sell five-star flags, I'm not going to attack you for that, regardless of the symbolism of that act.
EDIT: On the topic of hatred between the groups, there isn't really much hatred toward individual mainlanders; the island is a top tourist destination for a reason. Mainlanders have a good time here, and plenty of Taiwanese folks have family back on the mainland. So what if someone is pro-independence? There's a crowd of aunties and uncles who march down the street from Taipei 101 every weekend, singing "China is China, Taiwan is Taiwan;" does any sane person think these people are a serious threat to Chinese hegemony?
