Literally Animal Farm

When someone who claims to support a group or cause betrays it after gaining a position of power.

Cobalt: You said you supported freedom of speech before becoming a moderator, right?
Sapphire: I did.
Cobalt: So why did you ban a guy for talking about government collision?
Sapphire: Because no one should believe those lies.
Cobalt: *sigh* Literally Animal Farm.
