McDonald's is said to be planning to sue people who have been refusing to buy its products over the past months leading to their $1.3 million loss. This is due to a boycott movement where people in a lot of countries are sanctioning this company because of its support of the Zionist regime that is occupying Palestine and is committing genocide there.
Imagine if some day you are out and about, suddenly someone wearing a chicken suit puts a gun to your head forcing you to buy their fast food or they'll shoot you

I think they can only sue those who are involved in that activity if it is unlawful to boycott someones business. If it was covered by the Sherman Anti-Trust Act that I found on google then it is illegal.
