There is some irony in a newspaper attempting to shut down free speech (parody is generally covered as such), and even more so considering it's a left-leaning newspaper yet they chose a very capitalist way to go about it (by hiring a law firm to sue on copyright grounds).
It's a joke. Now they can't take a joke or let alone meme or create parodies and remixing images for laughs?
Maybe they should keep their guard down for once.
