Maybe because a tech industry forum routinely circumventing copyright protection paywalls in a "grassroots" way is in questionable taste, and making it official would arguably be worse?

(Incidentally, someday a piracy site like that could serve up a browser zero-day, and pwn a large percentage of US tech companies. Without ever having needed to go to the trouble to develop their own content that would attract such a large audience of tech workers on work machines.)
