The WMF has "Wikipedia" trademarked, doesn't it? It looks like a cut
and dried case of trademark infringement to me. Whether it's worth
doing anything about isn't up to me, but I reckon something could be
done if it was wanted. (If memory serves, you have to actively defend
trademarks or risk losing them, although I'm not sure if that applies
to this kind of infringement - they aren't calling an encyclopaedia
"Wikipedia" so it's not making the name generic.)
