Byku I don't see particular interest about privacy in the general discourse right now.
There might be two things at play here. One, people are likelier to complain if they believe something will directly affect their life, and two, we have much better privacy solutions today technologically, which may also cause some complacency.
Some 15 years ago, everyone was file sharing, because there were no realistic alternatives to get movies and music, and much of the pushes against privacy was either motivated by catching file sharers, or either way widely recognized to have that effect. I am not surprised people used to complain a lot more, because they very much felt the threat. It would be them who was going to go to jail if these anti-privacy laws passed.
Today, we have completely legal, ad-free and fairly cheap streaming services like Netflix, Spotify and so on. Barely anyone file-share anymore. If a law would be proposed that would make it easier to catch file-sharers, barely no one would care, because they would not think it directly affects their life.
On the flip-side, today we have Tor. Tor Browser is one of the most downloaded web browsers in pretty much all app stores that has it. It is a very strong and widely used privacy solution, and I think there is a lot of complacency among users of Tor, since they don't feel Chat Control laws will affect them. They have access to probably the biggest darknet too, if a need would arise. Even VPN users may be complacent, since they may feel they can just exit from another country that does not implement similar laws. My perception is that not even children feel Chat Control would affect them much, given how eagerly they were to ditch Discord and move to the much less moderated Matrix network when Discord threatened to implement age verification to block access to porn. It was effectively a large-scale boycott of Discord. At least from what I heard. Discord delayed their decision to implement age verification globally because of it. I think everyone feel it will be too easy to circumvent these laws.
After all, no one is targeting Tor or VPNs or other anonymity networks. And if they do, well, China has been trying for a very long time, and people still find ways to get around the blockage.
We still need to fight these laws of course, or a day may come when it is not so easy to circumvent them anymore. Because it surely isn't in China, it is possible, but requires effort.
