Let's assume movie tickets are free. Unless the ticket explicitly says, "You must watch the ads for this ticket to be valid", you're under no obligation to watch the ads before a movie, even if the theater's business model is dependent on your eyeballs actually seeing the ads. If that business model starts to fail because more and more people are realizing they don't have to watch the ads before a movie, you can't blame the people, you have to blame the business model. There's no reason to have a moral obligation to abide by some implicit non-legally binding contract, especially when that contract involves the invasion of my privacy and subjects me to potential violence.
