Stadium screens are censored, and phones ended that

Rules limiting big-screen replays of contested decisions were written for a crowd that could not see the footage any other way.

The convention was straightforward. Do not put a contentious replay on the stadium screen, because forty thousand people watching an incorrect decision in slow motion is a public order problem before it is a sporting one. Competition regulations in several sports still carry a version of this, sometimes explicitly, more often as a strong understanding between the governing body and the venue's production team.

It made sense in an era when the only screen in the building was the one on the gantry.

Now everybody in row Z is holding a device that can rewind. The replay the venue withheld is on the phone of the person next to them within about eight seconds, complete with a commentary line telling them the official got it wrong, and often with a graphic overlay the official has not seen. The rule has not stopped the crowd learning anything. It has only guaranteed that the crowd learns it in a fragmented, partial, maximally inflammatory form, from whichever clip travelled fastest.

That is the reverse of what the rule was for.

The venues that have worked this out show the review footage now, and show it the way the review official is seeing it, sometimes with the audio of the process. When a crowd watches the same evidence in the same order as the person deciding, the temperature drops. When they watch a fourth angle chosen by a broadcaster to be maximally damning, it rises. Same incident, different governance.

There is a control problem underneath. In most stadiums the production feed and the world feed are separate operations, and the venue director does not always control which angles are available in the bowl. So a rule that says show only the approved replay depends on a technical relationship the rulebook does not describe, staffed by people with no officiating role at all.

I would go further than most. Make the review feed a mandatory in-venue output, with the same delay and the same angles, and make it the only replay the screen carries.

Not because transparency is fashionable, but because the alternative is a crowd being informed by a source with no obligation to be fair.

The censorship rule already lost. Nobody has bothered to rewrite it.
