Yea, about that thread, I just read the whole thing, and while a bunch of posters were accusing everyone of being sinophobia, no one said anything negative towards the Chinese people, they just expressed concerns towards Tencent being an arm of the Chinese government.
China isn't a democracy, so when powerful Chinese companies that have to operate in China start buying large chunks of non-Chinese companies, people are going to be a bit anxious. that's not sinophobia. This reminds me of the current "russiaphobia" that is going around.
I probably worded that wrong, the thread was more closed out of accusations of sinophobia towards the OP and the tweets quoted. I'm Chinese myself and I still say fuck the CCP, I know the difference between people talking shit about the government and actually being racist.
Either way, I still think the sources of this supposed 30% stake are dubious. No one seems to have dug up anything further or bothered to really investigate to verify this. Even if the source seems trustworthy, it's still just one person that has looked into this. 30% stake isn't majority ownership but it's a huge chunk and a big cause of concern if true, and I'd be VERY concerned if this was somehow managed to be hidden for at least a year.
