About [[MediaWiki:Wikimedia-copyrightwarning/en]]
I changed it per Philippe Beaudette. I'm not going to change anything without a clear change request from WMF legal.
They say that it's up to the community to request the change, but the community never requested it, so it should be reverted. Anyway, this is the usual dead end, so I'll change it in all languages myself, except English 1) because I can't, 2) because I don't care. I hope the wrong default won't mislead too many translators.
If you really think it's wrong, I guess you should persuade the Wikimedia legal team of their wrongdoing, but I understand if you don't.
I've not full understood the problem but, if a default is possibly misleading, please advise via message dcumentation. When translators are aware, they'll likely not be mislead.
Yes, it's what I did. Thanks.
