Since you asked what I think, I will reply. To me this is, to put it mildly, very strange. Under the assumption that nothing bad happened to Maxine, there is an extremely limited pool of possibilities where it would make sense for her to then just disappear wordlessly. Because usually when someone disappears like this, it's not because "they are just taking a break" or similar.
One does not "take a break" by disappearing suddenly for over a year without saying a word.
The fact that Cobra didn't say anything to logically justify this leaves things with no more than two possibilities. Which is one, there is something that happened that he does not want to speak about, or even is uncertain about, himself (for example the Magnum Opus theory of yours, or other theories like Maxine being taken to the Gods etc). Or two, that she did not leave out of her own will for whichever reason, with circumstances that didn't even let her write anything about this on here.
What I find funniest most above all, is that 99% of people here simply accepted what was said blindly like sheep without even questioning anything. Although I cant say I'm surprised.
Maxine has said plenty of times that the Truth doesn't fear questioning, and that blind faith is something that the xians do. Honestly, a lot of people should be asking questions here considering the lack of any concrete information and details about the literal founder of the JoS disappearing wordlessly. All we got is "Maxine stopped talking to me in April 2020 and has been gone ever since. But she is safe so just take my word for it".
