But you're claiming to be the sole arbiter of facts, without any evidence yourself! It's your opinion that this person's feelings are gullible. It's also your opinion that the intention of these reports are merely vengeful attacks.
I think it's entirely plausible that the internal politics at Lucasfilm have gotten very nasty, I even think it's plausible that certain decisions may have been "hidden" or conveniently omitted from reports for longer than they were supposed to. While I certainly don't find it plausible that this whole Luke-Mandalorian scenario played out exactly as described but when it comes to these sort of internal corporate power struggles, the industry press tends toward hyperbole and exaggeration.
But again, that's my opinion
