Life goes on fine without knowing who all the people are in courts around the world are right now. Unless the public is involved or impacted, or there’s an entity like a business or association on trial, I don’t really see what lacking the choice of anonymity does to help anyone, especially the innocent.
I’m no lawyer though and it’s surely not as simple as that. But just like anything involving personal or sensitive information about a person, it should be protected. Especially when, at least in principle, the justice system is there to protect, under innocence until proven guilty with no bias.
