Sure, it’s unjust that innocent people lose everything, but... every single day innocent people lose everything because of the legal system.
“Innocent until proven guilty” may be the best we have for a legal standard but it is far from perfect and applying it anywhere outside of the legal system is a mistake regardless of how you feel about innocent people losing their careers through the court of public opinion.
Outside of the legal system “innocent until proven guilty” is a very common cause of the revictimisation of victims.
