I thought similar about tornado cash recently too though. I don't know if that can be traced because I haven't investigated their source/algorithm but I think the news articles about that have been great advertisement for it.
The founders of most other high-profile mixers have met terrible consequences, yet for some reason - even after 5 years in operation - ChipMixer has avoided all sanctions and much political attention. I'm not a conspiracy person and prefer hard evidence before making conclusions, but CM being a honeypot would explain a lot.
Bitmixer lasted 6 years until they shut down and didn't seem to face many consequences. Bitmixer was a big team, chipmixer gives an impression of being small, I think it's possible chipmixer used what they knew from prior mixers and used it to their advantage - with staying fairly anonymous. The history of bitcoin mixing is large enough to include one mixer in 40+ that manages to maintain its privacy.
Even before recent events & revelations, I think you'd have to be crazy to use ChipMixer to mix coins. Unless you are highly schooled in blockchain OpSec and possess the utmost mindfulness when spending mixed coins, there's a good chance Chainalysis could deanonymize your BTC if they really wanted to.
I think this is how chipmixer remains functioning too. If they give you limited chip sizes, they give you an incentive to donate back change rather than joining mixed funds and making users more traceable.
Most privacy tools available are too advanced for the average user imo and probably a lot of advanced users. You don't need a company to do chain analysis to denonymise you, just an enthusiast with an hour or two to spare (or less).
Governments haven't banned no log VPNs from being used yet, and I think that would likely be the area to look into if they wanted to prevent illegal activity since they'd want to have access to that data ideally, even though I still wouldn't agree with that.
So, taking that into consideration I don't think it's much different form this scenario. There's going to be a lot more people using no log VPNs as a way of aiding their criminal activity, yet the government haven't appeared to have much of a problem with it, likely because they identify that the mass majority are using it for legitimate reasons.
There's a use case for VPNs improving security of companies and aiding in certain things (ie storing and processing personal information in one territory while accessing non sensitive information outside of it).
No log VPNs are generally well marketed on increasing security and privacy of users (especially on public WiFi) but I'm surprised they've lasted so long and become so widespread.
