I don’t understand why we can’t name and shame these days

Power. Respect for authorities.

You need to be hired somewhere else. The new company you apply at don't know what actually happened, it's all hearsay and bad employees may make shit up to get more pity or make them look less bad if they were fired for legit reasons. In the confusion they'll want to defend their interest, and some may just be bad people to begin with.

And then there might be repercussions because they have more means than you do.
