That's a valid question, but luckily we don't have to address only one or the other possible foci.
If the primary concern is "Roget derailed the thread about Soulless and turned it into a thread about Cyan", that's been discussed already (per WJS' original post, first question).
If, however, the primary concern is "Roget expressed his concerns that Cyan's behavior could be considered abusive", then, um, I don't quite know what to say without devolving way outside decorum and professionalism. Again, Roget offered his informed opinion and, when challenged, provided logical reasoning for his declaration. If Staff cannot express reservations about a user's behavior, any user's behavior, especially one who is up for promotion, then how are we to effectively discuss any user's situation?
I don't believe these are the only options for interpreting the complaint. However, further explanation would risk turning this from a thread about Roget's behavior into a thread about Cyan's behavior.
For the same of completeness, though, I will add further information about the original complaint, posted by Cyan in 17 that fateful night:
10:58:05 PM C<Cyantreuse> WrongJohnSilver: My other aspect of the compplaint against roget is "18:18:44 <Cyantreuse> What is the content of whatever it was that you saw. 18:18:58 That prevented my promotion. Procy says it was "logs." 18:19:25 <Roget> You behaving terribly towards other people"
No further clarification was given by Cyan. For context, the relevant portion of the PM discussion between Cyan and Roget, which Cyan provided for that other thread:
18:18:44 <Cyantreuse> What is the content of whatever it was that you saw.
18:18:58 That prevented my promotion. Procy says it was "logs."
18:19:25 <Roget> You behaving terribly towards other people
18:20:03 In a way which I felt was manipulative which is a very dangerous quality to have in a staff member
18:20:45 <Cyantreuse> If you cannot handle this topic in a reasonable manner, I will officially complain and move to someone else. I am mentally ill. I spent two weeks in a psych ward for a suicide attempt. I was diagnosed with MDD, BPD, and Panic Disorder. I am on meds. I am fixing myself. If you cannot show me my own alleged speech that I myself typed, that is a problem.
18:22:31 <Roget> In what way has my giving you an honest response of what I saw not reasonable? I didn't keep copies of the logs but I did look over them thoroughly at the time, and that is my opinion from what I saw.
18:23:04 <Cyantreuse> "you behaving terribly toward other people" is an intentional jab and an unprofessional statement.
18:23:37 <Roget> I don't mince words. Sorry if that
18:23:47 s upsetting for you, I can try to fins other ways to say stuff for the future.
