I wonder if Recap [1] would help in addressing the censorship/deletion issue. Ultimately, the way we fund these programs is the root the problem (and the privatization of what is supposed to be public data).
For example written opinions that "set forth a reasoned explanation for a court's decision" must be free of charge.
They make it is as difficult as possible to access this, and do not allow any sort of bulk download, because doing so would make PACER/courtweb less useful as a pay service.
