Thanks for the useful advice, I’ll keep it in mind going forward. There has been no pushback so far because of that poor choice of words 
I’ve seen my share of “diversity-washing”. And “free-software-washing”. And … They all have one characteristic in common: people involve don’t actually think about the topic, except for advertisement purpose. And they do not spend time on the topic.
Regarding diversity, I intend to continuously work on improving it or maintaining it. I hope other people involved in fedeproxy also care about diversity on a regular basis. But even if none else does, I’ll keep at it.
This is a horizontal community and there is no higher authority to dictate what should be done by who. Only how they should be done, i.e. within the boundaries set by the code of conduct. As a consequence, there cannot be a spokesperson since noone has authority to say we regarding fedeproxy. There only are people who act for the project in their name and can say I will or talk about the fedeproxy project, not in the name of the fedeproxy project.
