What is interesting to me is how in good conscience you can just grift like that, when you are already making LOTS of money off a crisis in a Church. Is there not a conscience that hits you? At least a little bit? I couldn't live with that.
Oh, I agree. And there are some honest types who took a serious hit for their consciences: Gerry Matatics and Patrick Coffin come to mind. Matatics was at Scott Hahn levels in terms of what he was doing, going on tours, probably could have gotten in with "Catholic" "Answers" and EWTN, but gave it all up (even if you don't agree with him) to be true to his conscience. Coffin was an EWTN personality, getting much revenue from his activities, but he's now given that up to become a Bennyvacantist (even if you don't agree with it).
As for the others, they make LOTS of money, but they're not fabulously wealthy, and they're terrified that their revenue streams will dry up, since the alternative would be that they'd have to go out and get real jobs. I've heard that Marshall makes about 200K per year from his Patreon channel, and probably has other sources. But if he lost 3/4 of his audience by coming out as, say, a sedevacantist, he would have to start draining his savings.
You'll find that there are no wealthy sedevacantist or even Traditional Catholic (in general) grifters, because their audience is far too small to generate any kinds of serious revenue, and their audiences typically include large families who don't have a lot of spare money to support them.
