Matthew Inman's response to this whole sorry affair seems to be primarily that he wants to write comics and not play at being a lawyer, and he'd prefer it if people just let him get on with that and enjoy the results. Given the flagrant copyright violation of the other site involved here, and the nature of the lawyer who is chasing Inman right now, I think he's been remarkably classy.
I suspect a lot of people in his position would instead have lawyered up, gone after the other site for a retirement-level scale of statutory damages, and gone after the other lawyer personally with the intent of ending his career. Frankly, I wouldn't blame them, and I almost wish Inman would do that as a matter of principle. However, I have to admire his focus on doing the work he wants to do and his choice to do something socially useful to make his point instead.
