No, I have no problem with him accepting a paid writing assignment.
I have an issue with Owen's REASON for giving him the assignment and Sungenis's agreement with it: Owen seeks to squash the discussion of flat earth. It's very important to him.
Sungenis's partner, Rick DeLano, has a very irrational hatred for flat earthers, which stems from the fact that 3 major flat earth YT channels released FE films just prior to the release of The Principle, and they went viral and it killed his movie. Well, DeLano's bad publicity killed it too, but I digress.
Sungenis likely will not debate a FE Catholic if he's wasting time with clowns like Subirats.
