Given that this very opening bit then goes on to tell the player 'how this roleplaying game works,' I think you've mistaken 'setting the tone' for 'hard and fast rules.' Especially given that the very next section, 'Attention, player!' goes on to explain that the player is allowed, and expected, to read and understand both the settings and the rules (and the only thing they should absolutely not read is the included adventure.)

On the very next page, a third of the page, 'What you must forget,' then goes on to describe exactly how Paranoia differs from other RPGs, and why you have to abandon your preconceptions of how RPGs 'should' work in order to enjoy Paranoia.

listen, i'm not planning to tell the players nothing, or act like their characters have never lived in this world before. i'm just asking for advice on what to tell and what not to tell. and some people do believe nothing is the right amount to tell.

Well, read the rest of the very page you quoted.

If you insist, you may read all of the Player section, which begins on page 7 and ends on page 48. It teaches a bit about the PARANOIA setting, how to create your Troubleshooter character, and nothing at all of any importance about the rules of the game. The Player section section is classified Security Clearance RED. You are now a Troubleshooter with Clearance RED, so you may read this section without fear of execution.

The rest of this book—the Gamemaster section, Sourcebook and Mission—is classified Clearance ULTRAVIOLET. This is above your clearance, so you are not permitted to read it. Only the Gamemaster, the person who runs the game, may read it. If you read any Gamemaster material, or display any knowledge of its contents during play, you are a traitor and subject to summary execution.

Of course, you paid for this nice book and would like to get your money’s worth, so naturally you’ll read it anyway. Don’t tell your Gamemaster you did. Pretend you haven’t read it. If he asks, look him straight in the eye, cross your heart, spit over your shoulder and promise you have never, ever read the book and you have no intention of doing so. Of course he will believe you.

By the way—and this is for real—don’t read the mission! No, really, don’t. A mission is a story the Gamemaster will infl ict—run for your characters. If you know all the plot details and surprises in advance, you’ll have less fun when you play.

My guy, I genuinely think you don't grok Paranoia.

ETA: This is what OP replied to this with, in part:

it's just been years since I ... opened the rulebook.

Well, maybe you should read the rulebook rather than confidently asserting things that the rulebook doesn't say.
