That’s a lazy straw man. The difference is proportionality and target. Enforcing a law against individual wrongdoing isn’t the same as redesigning society around mass suspicion and fear. “Chat Control” doesn’t punish a crime - it manufactures a climate where everyone is treated as a potential criminal, and coerced into self-censorship. That’s systemic intimidation, not law enforcement.
You don’t have to enact laws like Chat Control (literally Speech Control, they’re not even pretending to try to hide it) to have tyrannical government.
To have tyrannical government we only have to have governments who want to propose such legislation.
Any reasonable sort of government would be highlighting the absurdity of such ideas and speak out against them.
