That is were you are wrong my friend... political conflicts affect us all. Whatever political decisions politicians makes affects everybody directly or indirectly, this includes business sectors, religious sectors.. practically everyone that is part of that society. Let say that a political decision has been made that will directly affect farmers sector and you are in the labor sector, it will indirectly affect you of course since you buy products grown by the farmers. That is why it is very dangerous to say that let politician deal with politics without your attention at all because your might wake up one day not understanding why you are jobless, why the gas is too high, why you can't afford your medication and there is no health care for you, why you are homeless or why you are in prison and of course dead can no longer wonder why they are dead. That is why it is very important that each of us must have some level of political awareness. If you don't have some level of political awareness then I guess it is right to say that you don't have the right to complain.
Another thing is China and Hong Kong have different government because of the "one country, two systems" principle. The Great Firewall of China does not apply to Hong Kong and for that reason China can not demand that Hong Kong ban apps that China doesn't like. This is the reason why Google and Facebook is still accessible in Hong Kong.
Among tech companies, Apple is one of the most successful in doing business with China. Facebook and Google are not successful at all even after many attempts. However, the success of Apple in China is becoming its biggest problem. They are now very dependent on China specially with their production line. They can not just pull out of China overnight without incurring huge loss. Because of this China can literally bully them to submission. I guess Google and Facebook is feeling relieved that they have not invested in China.
The reality is China with its huge market will challenge the western world and even the rest of the world. In this economic conflict, foreign companies that relied so much in China will be the first casualty. Apple is in a dangerous water right now, if the conflict between US and China intensifies they might become the first casualty. I guess it is a right move for them to start looking at India for its production line before it will be too late for them.
