Not that I regularly indulge in reading the Daily Mail, but I came across this article where it was reported he's been sharing the donations he's received from supporters to help other folks in prison afford food and supplies from the commissary.
For those that don't know, prison commissary supplies are extremely overpriced. According to The Appeal, items typically can sell for 5x times more than their market value and some items have a markup of 600%. This is on top of the fact prisoners are often forced to do hard labor in unsafe environments while making less than a dollar per hour. These prices add up fast and are a source of financial burden not only for prisoners, but for their families since most prisoners come from impoverished backgrounds because of America's two-tiered justice system where the poor are unequally targeted and many times for crimes they did not commit.
A lot of the people who are in prison are not there because they committed a crime, but because they were in the wrong place, at the wrong time, and could not afford a lawyer. These people are given public defenders and basically forced into taken a plea bargain or a jacked up sentence then end up being subjected to what is literally slavery (as per our "wonderful" 13th Amendment) and being forced to spend what little pennies they make in what is effectively a company store.
The people who were skeptical about Luigi because he had some cringe opinions and bad politics were wrong. He's a good guy and people are complex. Sure, he's from wealth and it was his circumstances that made him a traitor to his class and a hero to ours, but we are all shaped by our circumstances.
Sometimes Gotham's best heroes are the so-called villains.
