You've already admitted you gave up after a couple of pages.

Which parts are you disputing?

Even the first page, it implies it is made by the original designer. It is disingenuous from the start. And actually i looked a few more pages, the quality of the content is quite bad.

Let's look at what the PDF file says:

Leah Elliott

Contra Chrome

... a little down in the address bar:

"Remixed from Scott McCloud's Google Chrome Comic"

Next page: Again "Leah Elliott" and "Remixed from..." notice.

So the actual "remixer" isn't hiding or anything.

On the actual webpage, there's an "About" link, which is not hidden or anything either.

If you click through the link to the website (instead of the PDF) it starts you off on the first page of the comic (not the introduction) with no indication that there are earlier pages. Which means it starts off sounding like it is something Scott McCloud wrote.
