~ that decided to accept the trade-off.
You are belittling their cooperation with anti-privacy organizations to deanonymize their own service by calling it a "trade-off"!
If ChipMixer, a centralized service, also decided to accept the trade-off, it would personally be OK for me, because I accept that being a centralized service, they have their own right to decide which path to take the service to the future.
The problem is that when mixers do what you are calling a "trade-off" they stop being useful because they would no longer be mixing anything anymore.
