Those aren't actually specifics, those are all fairly vague. Specifics would come if someone like Phillips or the org offered up more than "no comment" when speaking on record. For example, what alternative position was offered, why did Phillips choose to leave, why did Weir get let go, why did the charity fail to raise more money, what other avenues did they persue for Donations than just the 50/50, and the list goes on.
I'm not trying to paint anything, I just added that Mendes is writing about his impression that the org alienated him in response to you making assumptions about the type of alternative position Phillips was offered and why he wasn't interested.
