You presume that most people will find out. As the article says:

Curiously, information regarding Barrett’s being born a biological male is not mentioned anywhere in her own biography or in reports on her athletics.

So yeah, if you actually watch the event and see this guy's face, it's not hard to figure out, but I predict little to no coverage on this sort of thing. Hell, even THIS article calls him "she" throughout. They've redefined terms to the point that it's basically career suicide to even report on this sort of thing honestly, that is to say, using actually correct pronouns, and it's not much better covering the wider implications that men and women are physically different. So people will experience first-hand an example or two, just like has been happening for years at lower levels of sports, but there will be no mainstream coverage of how widespread it is.

It's kind of like affirmative action: It's widespread, it affects almost everyone at some point in their lives, but most people only notice it around them personally a few times, and journalists, even right-wing ones, generally refuse to report on it because of the political blowback from doing so, so most people just forget about it.

So yeah, if you actually watch the event and see this guy's face, it's not hard to figure out, but I predict little to no coverage on this sort of thing, just because it's practically a career-destroying event to publicly admit that men aren't women and physical differences between men and women exist. So people will experience first-hand an example or two, just like has been happening for years at lower levels of sports, but there will be no mainstream coverage of how widespread it is.
