So what? It's a comic strip, for crying out loud. It's not like DFX is advocating this sort of thing in real life. In a way, he's making fun of it. Dilbert depicts business practices that make Lydia look like a saint, but I suspect you don't rant about them.
no. thats called ruining someones life and then trying to extort money from them. not only is it moraaly deplorable, but it's actually illegal not to provide her with the cure for free due to lydia being responsable for her condition.
spidergirl should just go to the police and have lydia's shop closed and her arrested.
