I'm going to be pretty cynical there. China's shown it is willing use force (and bigger army diplomacy) if necessary. Spreading the word about this in China's even more difficult (internet censors). Unless the CCP buckles I can't see HK coming out on top.
I know and I don't even have a VPN. I'm sure its getting around among those who care.
I don't think China will involve the PLA in this; that would cause a huge scare internationally. Instead, they'll just let the HK police deal with it (and they seem to be hard enough). The HK elite basically run the territory and are incredibly friendly to the central government.
I think the outcome of this will be super interesting. HK is now a part of China and I'm sure that the CCP is concerned that these protests will spread to the mainland.
My guess is that they will handle this in a very non-public way (no surprise there!) working through the HK authorities. It will be brutal, but the CCP knows what a heavy hand will get them (Tiananmen Square).
Unfortunately it's very unlikely this will spread to the mainland. Much different from 1989, 100% of mainstream media in the mainland is heavily censored. They have been brainwashing the last two generations for tens of years. If you go weibo (Chinese version of Twitter) you will see the majority of mainland Chinese think the unarmed students were extremely violent and the police should shoot them.
The CCP has been doing very good at creating class conflicts and isolating enemies.
