I don't mean to sound crass but is this really a surprise to anyone? I mean Yahoo has been a "dead man walking" for a decade+ in my mind. What did they do successfully? After they lost the search game to Google they stopped doing anything of note (Yahoo Pipes was cool and Flickr I guess, 2 more projects they destroyed/killed off). I think Yahoo News was a thing but I've never heard someone mention it in real life, I assumed it was like the older population still using/paying for AOL.
The writing has been on the wall for way before a private equality group bought them (which should have been a clear sign if somehow you were unaware it was dying). I'm shocked that employees there are "shocked".
