Wp copyright quote
Well spotted -- I will need to adapt the wording of the template. In the majority of cases the template is used for an extract of an article -- but I guess we should also cater for a full article scenario. I'll take a look at the template and fix this.
A quotation like this would qualify as fair usage. Its properly attributed and clearly states the license. Technically we could also use all-rights reserved citations within a CC-BY text under the provisions of fair usage / dealing.
So in this scenario -- there is not a license conflict and we're OK.
Thanks for asking.
