Hum I read that more as, we need it secret or corps providing us info will never accept to do it and will fight to the end even if they are legally bound to provide the information. So it's not that they don't want challenges it's that they think they can't even get what they legally can without secrecy. It's not a very good argument by the FBI for sure. Obviously if people knew that some corps provided info but not other, it could penalize the first by losing customers but we already know we can't trust certain companies even with all the secrecy.
