This is a weird take. You're strawmanning hard here. Who was attempting to equate real life election fraud and vote manipulation? Completely separate things.
Also, vote manipulation is bad and should be avoided where possible. It undermines the purpose of voting, which is to allow users to determine what good content is. If vote manipulation is allowed, someone could decide that their content is good all on their own.
My guess is that they received an email with some preamble to the important bit. They only screenshotted the important part, but part of the rest of the email was included.
