It looks like we have far more serious problems than just following the CoC in every thinkable correct way.
The engineer from the machine room reports to the bridge:
The ship is sinking. Give orders.
Response from the captain at the bridge:
First of all you have to call me Sir. Also when asking for orders, you should always be polite and add a "please" to your request.
What I want to express with that example, is that there's no real benefit in polishing language without addressing the core problem (the sinking ship).
There are several sites in the SE network (let's say Stack Overflow is the flagship), where new users complain about feeling unwelcomed, and don't understand why their questions or answers are downvoted or closed.
These users tend to take it personally, and will resort for any kind of claiming to be bullied because of their gender, cultural background, or whatever reason to find they feel discriminated. Probably along with flagging comments or answers as rude or abusive.
Let's remind ourselves what is the primary goal of all SE sites: To have a repository of FAQ-like questions and answers that will be helpful for future research.
If it's not like that anymore, I'd like to hear a profound statement from the newly-installed CEO, and what are the changes taken and why.
I believe it's impossible to cover every possible personal concerns of every user in a neutral way. Regarding the recent hype about gendered pronouns, some will prefer they and others will prefer he or she, but in the end that doesn't affect the content of questions and answers, instead it only distracts from the goals I believe we have here.
Finally, I hope to have a concise answer from the captain as to what the course of action will be and where we are navigating.
All in all it's the main duty of a CEO to explain what the company policy actually should be, and where they think to steer to.
Prashanth Chandrasekar could fairly do better about that.
As some people were complaining in comments about unfairness against the new CEO:
Well, he's (I hope that's the correct pronoun used) here just for a few days now. Though it would have been a good behaviour to introduce themselves to the community via a featured meta post. Only seeing that change at twitter is a bit poor (at best).
Also a new CEO seeing that there is a crisis upcoming at their company as recently noticed, could simply jump in at least with a silly phrase like "This will be thoroughly investigated and discussed at a board meeting".
