If you're talking about Yahoo Games, remind me what original titles they had? Because I can't think of any offhand, unlike the GDC which offered Cyber Wars, Treasure-Crypt, Battle Things, etc. All of those are lost to time. Yahoo killed *all* of that. Yahoo was the direct cause for those things no longer existing.
Then I have a secondary beef with Yahoo over its non-stop security issues and the fact it erased my old email addresses which caused me to lose out on both memories as well as the ability contact old friends who I had lost touch with.
Not Yahoo! Games, I didn't even know that was a thing. I mean stuff like Yahoo! Answers, Yahoo! Groups, Yahoo! Instant Messenger, etc.
