I would argue it's a moral issue to pass a law forcing someone or businesses to pay for something against their will unless they've caused someone or someone's property harm. So, I don't think they should have to do anything with the profits THEY'VE earned that they don't want to (going forward). However, they did cover up legit studies on brain damage and lied about consequences of head trauma for years, so I think a huge lawsuit for damages should be levied against the NFL to pay former players that were harmed by their actions.
