I lean towards adopting the KDE Code of Conduct. There has been some legitimate controversy surrounding both the Contributor Covenant and the GNOME Code of Conduct.
Lunduke’s video on the GNOME CoC:
Reddit comments, which are (surprisingly) mostly civil:
The KDE CoC uses straight forward English, while both the GNOME and CC have very ‘American’ English, using words and tone that would not easily translate or be understood by non-Americans.
There is also a lot of discussion concerning pigeonholing discriminatory behaviour in the Contributor Covenant. This makes both enforcement harder, and it also makes people forget that other forms of discrimination are also not tolerated. KDE sitesteps this issue by explaining, in more detail what the intent is of the Code of Conduct.
KDE expresses itself a lot more in a Civil Law manner, and not in a Common Law manner: intent and judgement over hard rules.
I fully support the idea of adopting a Code of Conduct, and I think we should certainly make a clear statement about what kind of group we want to be. Thus, if this comes down to voting, I’ll put my vote on KDE’s policy statement.
