I am BEGGING people to understand that "but that's illegal" does not, in fact, mean that somebody can't do that.
Seriously, today I've heard "no, that's illegal, that means they aren't able to do [thing]," "if it was illegal, they wouldn't be able to do [thing]," "but the law says they have to so they have no choice," and "won't a judge show up [at the dispute site] and make them?"
LAWS AREN'T MAGIC.
