This is verging on derailment but Jim has no reason to say anything for or against Ralph. They aren't connected outside of stream appearances at a time everyone universally accepts nobody cared about the streams because of Ralph, but purely because of the guests Ralph could get on. Jim's general receding from the Internet due to his declining health is as likely an explanation for why he doesn't want to get involved in this kind of thing anymore as he doesn't want to be caught out on an autism crusade again like he announced with Sargon, or maybe he just never cared enough about Ralph in the first place to bother with him now purely for the sake of amusing other people. Take your pick.
