After thinking about it a little bit, I've come to the conclusion that, Palmer isn't dumb, he's just misinformed on the subject, just like the rest of the country was/is. His response is just like everyone else who just went by headlines that the press provided, he didn't bother learning about what went on, probably didn't know about the NFL lawyers admitting in court, to a judge, that they had no proof, probably didn't even realize that Brady won the 1st round in court. Why ? Because he doesn't care to learn or understand, just like the rest of the NON-Patriot's fans. Also, because it didn't happen to him.
Like most people, unless it happens to them, they just don't care, it's human nature. For instance, you think Michael J. Fox was donating millions of his fortune to Parkinson's research before he found out he had the disease ? I doubt it very much. Do you think Deangelo Williams cared about breast cancer before it affected his Mom ? So most people don't care about a negative thing, until that negative thing happens to them. Not everyone, there are thousands of caring people in the world, maybe millions, but it's just human nature.
