Agreed. I don't think that HK have an actual plan here. They just protest for the sake of protesting. China will never step down and if anything HK makes it really really easy for China to claim more control now over HK because HK proves itself to be not in control of its citizen. China is the most important market in the world, no other country will intervene with China, especially not given that the largest country in this world - Russia - would always back China in a geopolitical conflict, so nobody has the balls to challenge Russia and China at once for good reasons.

EDIT: Besides that, I am pretty confident that the media makes it look a lot worse than it actually is too.

I've been to China and Hong Kong. In China people looked relaxed, spent time relaxing in parks and socialising. I went to Hong Kong and it was unbearable crammed, people were stressed and over worked and there was no escape from the hamster wheel. No wonder mainland Chinese have little sympathy for HK.
