I only see not Chinese members that are surprised. And a member thinks all fast foods is unhealthy and garbage. Not sure why you project so much about what others think.
Beside, McDonald in China is majority owned by Chinese conglomerate CITIC. Burger King is not top 3 anymore. Also, it doesn't really matter as more competition the better for consumers. Dicos, a Chinese fast food, is now owned by Taiwanese. Yonghe King another Chinese fast food has been bought by Philippines' Jollibee.
The fast rise of Chinese fast food chain such as Wallace and Tastien as less expensive alternatives would probably remake the landscape of fast food in China very soon. Old chains such as Country style cooking, Real kungfu and Home original chicken are actually under pressure. Just like hot pot chain Little Lamb which was bought by KFC is overtaken by Haidilao and Xiabu Xiabu.
Just don't be a fool and act arrogantly like Samsung and Nike. Companies should stay away from politics and not acting prideful and arrogant and disrespect the local market. KFC is successful because it adopts quickly.
