This comic is no longer relevant; you can see every Game of Thrones episode in existence by visiting hbo.com, and following a very straightforward streaming sign-up process. The price of admission is cheaper than all the legal options the character tried in the comic.

I guess The Oatmeal author forgot to update their decade-old comic to reflect the current state of things.

They did manage to add an update to the bottom of the website though, which says "Please don't steal." This either contradicts the message in the comic or piracy only matters when it happens to Matthew Inman specifically.
