Why am I not nervous?
The guy that made Platinum what it is doesn't take garbage from anyone, and Tencent won't want to force him out because they know his reputation for quality games so they will appease him and not boss him around. If they do, he will leave and take all the talent with him. Their good ips are owned by other companies so this would leave Platinum as a void of nothingess and at that point who cares if China owns them? So either Platinum remains what it is, or everyone leaves to start a new company and no damage is really done.
