A critic you can't fire, because that's literally the point.

means A person or group whose job is to monitor an institution or industry for wrongdoing and sound the alarm when something's off.

from Literal first, long before it was figurative: a watchdog was simply a dog kept to guard property and bark at intruders. By the 1800s English speakers extended the word to human guardians — committees, journalists, agencies — whose bark is scrutiny and whose bite is public exposure.
