From the first article-

In a bitterly divided 4-3 ruling, the state Court of Appeals said the trial judge made a critical mistake by letting women testify that Weinstein assaulted them, even though their accusations were not part of the charges he faced.

The appeals court said the trial judge compounded the error by ruling that if Weinstein took the witness stand, prosecutors could question him on a wide range of “loathsome” conduct, including bullying and fits of anger toward associates.

So, again, a fuckup. Yes, it sucks that guilty people can be let off due to a fuckup, but justice systems should adhere to certain rules and treat people equally and, in this case, that’s not what happened. Yes, our justice system needs to be better about both, but complaining when things work as they’re supposed to even though the outcome is unfavorable and a guilty person goes free is silly.
