I dont want to make false conclusions but the operators of CM didnt even made an own based research hosting wise.
Besides the fact that these types of speculations have no productive outcome, I personally believe this is too far fetched.
After all, ChipMixer has been one of the longest-standing mixers out there, mixing a ton of BTC, meanwhile others have come and gone. Even to the point where a few months ago people started speculating whether CM was a honeypot.
To me, it looks like the ChipMixer operators have run it quite competently, with the one mistake (if actually true) to store 7 actual TB of data. What makes or breaks a privacy service (for me) is that they collect and store as little data as possible.
In a business context, 7TB is nothing. That's what people have in their personal home NAS systems. But for a privacy service, I don't know what kind of big files you really need to permanently store.
One remark: I had a personal theory that 7TB was just the amount of purchased server storage (again, nothing for a powerful / enterprise server), which was simply mostly empty. Law enforcement could have seized old, funded keys by getting their hands on the drives and performing forensic techniques to recover permanently deleted files.
However, since even chips created a few days before the takedown were affected, this is not really plausible.
If I was to use any mixer, I would just postpone the idea and wait for a month or so, to see how things move on.
