Scenario: McDonald's Australian division decides to donate large amounts of money to sponsor a children's sport league. That's good, right? Many of their menu items may be high in calories, but at least they're out there trying to get kids to be active and healthy. A few years ago, that might have been the case. These days it gets the corporate benefactor in question compared to a tobacco company.
The ubiquitous public health advocates of this day and age point out that the resulting positive publicity may improve the company's image and make some people more likely to eat there. Which, of course, is always bad. So the only way McDonald's, or any similar company, could possibly gain any praise from such quarters is if they were to run an advertising campaign telling people not to buy or eat any of their food. And people laughed when we told them the trial lawyers were gunning for the food industry next.
