That is devaluing the word abuse. A voluntary optional task which you can decline at any time, is not "abuse" no matter how you spin it.
You can look at any job and claim it can't be abuse because people can leave the job.
You ignore that leaving the job means loss of income, status, or worse even.
Like, imagine if the TSA strip-searched everyone. Pretty abusive right? You wouldn't say "I don't see how letting people fly is abusive".
