Underlined rather emphatically in The Diamond Age by the literal murder of the clichéd cyberpunk character right out of the gates. Quite an unambiguous statement about What Will Not Be Happening In This Book From Now On.

That's probably the key part. If someone goes in expecting earnest sci-fi like Neuromancer and the satire part doesn't click early on, they're likely to be disappointed. (That being said, IMHO there are some aspects of Snow Crash that come off as low-effort, independent of the satire.)
