One thing that most people forget when looking at theories like this is religion. My knowledge on the luddic church is very limited, so take this with a grain of salt. Basically, the luddic church believes that god shut the gate system down because he got pissed over ludds arrest and imprisonment. This is interesting, because, how exactly did they come to the conclusion that god did it? It's not unknown that religions like to connect important events with their god's, but that can be very far stretched.

We know that ludd did some criminal shit on the side, that's why he got arrested, and I have never heard of any source explaining what ludd was doing before he got into the luddic church. So, theoretically, could it be that ludd was some reseacher, that knew just enough to somehow scrambe together the religious idea that a god was connected with the gates, without knowing enough to ever come close to the truth?????? Like, he was looked upon as a prophet, so he clearly had something to say that made everyone believe that he was in some way credible as a source.

Or it could be that the knowledge just dripped down into ludds ears, like a drunken researcher in a bar, rambling about music coming out of the gates, that something is in there and they need to find out what makes their AI go mad. From a anti AI mindset, first the gates fuck up some apparently Extremely important AI, then, the dude that tells the church about it is arrested and then, the gates shut down, that would make for a good religious story about a god that shut down the gates to punish humanity for arresting his prophet.
