All that you need to do to destroy any entity is to win one small court case, then use that victory to expand and grow, until the exception becomes the rule. Fast food is next in line.
Sadly you do not even need to win. So long as you have enough “public interest” money to fund your lawsuits, all you have to do is keep suing and the defendant’s legal fees will eventually drive it into complying with your agenda.
KFC recently got one of these cases dismissed. Hopefully, there will be a similar result here before the lawyers run up too large a tab.
