Did you read the article? They specifically brought up the example of Chaplain being fired as "canceling". Also, your definition needs doesn't match common usage, or what happens. Here's a better one: Canceling (n.): holding a public person accountable for their actions by withdrawing monetary support. This can be done by not extending a contract; by termination of employment, contract, or the privilege of access to particular public platforms from which they profit, if the funding is provided on a contractual basis; and - wait for it - - by ceasing donations. Which is what the authors are doing.
