I have raised my concerns for this appearing to be an advert on IRC with RCOM the DEV team and then on-wiki with Philippe. RCOM have pointed me to the WMF and the WMF said it's not their problem and pointed me back to RCOM. There is a claim that the central notice was agreed with the community but this does not appear to yet be supported with evidence.
I have raised my personal opinion at http://en.wikipedia.org/wiki/Wikipedia:ANI#Harvard.2FScience_Po_Adverts where any of my fellow Wikipedians are free to add their own.
Note, during the IRC chat it was pointed out to me that Google or a telecoms company could easily be next, there is no restriction for central notices of this type on what logos or other forms of advertising they might carry under a claim that this would make the sponsorship arrangement clear. Considering Jimbo's statements that Wikipedia will never carry advertising, I think this puts us all in an uncomfortable position.
