The "This incident will be reported" message is being removed from user warnings in the sudo program.
The message used to indicate that an email had been sent to the administrator, but now whether or not an email is sent is configurable, making the warning inaccurate.
The message was also confusing for users because they didn't know who the incident was being reported to.
Comments on a Github commit about sudo reveal tangents about various tech topics from Unix to social media behavior, with the core takeaway being about how the sudo incident reporting feature is still present but only displayed if it's configured to be sent in the mail.
The sudo command's "This incident will be reported" message has been removed in a recent update as it was unnecessary and potentially confusing to users, but some still find it amusing and developers are concerned about the lack of tests that cover such critical infrastructure.
