I lived in Hong Kong until 1995. The Basic Law is supposed to apply for 50 years, so we should only be about halfway through that. The sense in the HK expat community at the time was skepticism that it would make it the whole way unchallenged, but that China "needed" HK, so it wouldn't rock the boat too much.
Of course, now that is no longer the case. Any optimism we had at the time of the handover was rooted in HK's economic importance but China went and built Shenzhen into a bigger, better Hong Kong within two decades. Still a Special Economic Zone but without all the pesky political baggage.
China has been extremely pragmatic and results-oriented. When Hong Kong was the most economically successful part of China, they were happy to leave it be and learn some lessons from it. Now the rest of China has largely caught up and it's time for them to make HK more like Shenzhen, rather than the other way around.
I think China played their hand too soon and the west is waking up to it.
Of course China is motivated to have Hong Kong aligned with it rather than flirting with the West. Whether the West is "waking up to it" is not so clear to me. The HK riots were a big deal in the Western media for a while but now we've moved on.
They weren't going to make big moves until they had built up their navy.

There were people making noise about China. But in general China was off most people’s radar.
The Olympia’s they hosted was when I personally realized China was a big deal.
