People does not seem to like that kind of Wikipedia donation advertising, if I understood you correctly.
At least in the sense that there's endless parodies and nagging about those ads.
It does however seem to work, since they raise money that way - and continue doing so.
Internet Archive do have a top banner which is quite neutral on most of archive.org (It's the blue ribbon thingie). It's not on the Wayback Machine though.
I dont think people would mind seeing that on the recovered sites. (Unless they do and I cant see it for some reason?)
