They’ve only mentioned it as one avenue of misuse.
It's not unthinkable to conceive a scenario in which this symbol is misinterpreted, loss of health or life or property follows, and the ignorance of the perpetrators cannot be pinpointed - maybe it'd be lack of proper education, maybe missing classes during military training, maybe seeing red-cross logo misused in games, maybe bad memory - the thing is that all of those explanations are IMO "reasonable", so we might want to do at least something about each of those (if possible).
