Yahoo sells out to Microsoft – Have they given up on search?

Experts have said for months that Yahoo has really given up the ghost, by "selling out" to Microsoft letting Bing run the search engine instead of Yahoo’s engine.
Yahoo’s apparently addressing that issue on their marketing blog discussing "the next wave of search" .

Yahoo posted how they are still creating innovations in search, paid advertising and consumer relevance.

Yahoo, I know your trying to remain viable… But the MS deal still seems like a sell out. Even if Yahoo does come up with all kinds of innovations in the search market, I still can’t see them being a viable business in the long term unless something somewhat dramatic changes in the background.
