It all depends on what you're censoring.
Is it a bad sign if CSAM, Personal (medical, financial, etc) Records, Snuff, and Malware/Ransomeware are censored? What about manufacture of WMDs, terrorism, hate speech? Free software, and copyrighted music? Historical records of genocide?
As an aside… the if there was a real system out there that was trustworthy, it would have all of this and it would be the evidence you actually need to trust it.
If someone had a secure system for some of the worst stuff out there and it lasted more than a minute, pay attention because they might have actually solved some real problems.
